Abstract:
Abstract The parameter εK measures CP violation in the neutral kaon system. It is a sensitive probe of new physics and plays a prominent role in the global fit of the Cabibbo-Kobabyashi-Maskawa matrix. As one of the first discovered sources of CP violation, it has been measured in experiment to permil precision. A simple reparametrization of the efFective Hamiltonian has been recently shown to drastically reduce the perturbative errors coming from the charm-quark corrections, making the electroweak corrections relevant. In this proceedings, I will present the two-loop electroweak corrections to ϵK .

Abstract:
This paper is devoted to reconsider the one-loop oblique corrections arising from the scalar superpartners in the MSSM, that is, the squarks, the sleptons, and the scalars in Higgs sector. We explicitly present the complete one-loop forms of self-energy corrections to the gauge bosons of SM electroweak gauge groups, as well as their descendants theS,T, andUparameters, which can be directly applied to constrain the parameter space of the MSSM. Our results about one-loop self energies are found to agree with Drees et al. (1992) and Pierce et al. (1997). Nevertheless, theS,T, andUparameters are not in agreement with Dobado et al. (1999).

Abstract:
Present status of electroweak precision tests via the weak boson masses is reviewed, emphasizing that the standard SU(2) × U(1) theory is phenomenologically very successful also at quantum correction level. In particular, it is shown that the latest experimental data indicate the existence not only of the whole one-loop corrections but also of the non-decoupling top-quark effects, independent of the Higgs mass, which are a characteristic feature of theories with masses generated by spontaneous symmetry breakdown plus large Yukawa couplings.

In this thesis we report and discuss the results for the first complete calcula- tion of the one-loop electroweak corrections for the two dominant processes of single Top production at the Large Hadron Collider: the tW-associated pro- duction and the t-channel process. We calculate the corrections working both in the Standard Model (SM) and in the minimal supersymmetric extension of the Standard Model (MSSM, as- suming a mSUGRA scenario), analysing the effect of the corrections on several observables and trying to understand whether deviations from the Standard Model prediction could be observable. The single Top production is the main source of information about the Top weak interaction, and a privileged laboratory to understand the symmetry breaking in the weak sector. Moreover at the hadronic colliders the single Top processes provide the only known way to measure directly the Vtb element of the CKM matrix, providing a fundamental test of the Standard Model struc- ture. For the tW production process we present the complete calculation of the one- loop electroweak effect, including the effect of the hard real photon emission; we combine our results with the available calculation for the QCD and SUSY QCD corrections, providing a complete one loop description of the process. Our interest has been concentrated on the particular quantities that we have defined as partial rates, with special emphasis on the low (400 GeV) final in- variant mass. In this region with the addition of SUSY QCD one-loop terms, the genuine SUSY contribution reaches an interesting 10% size. The analysis of t-channel process is limited to the pure electroweak componet (adding the soft photon emission only, to cancel the infrared divergences aris- ing from diagrams with virtual photon). The electroweak corrections for the t-channel are less sensitive to the presence of the SUSY particles: this conclusion holds for all the four examined bench- mark points in themSUGRA scheme. In addition, considering the small contri- bution of the known SUSY QCD corrections, we conclude that in themSUGRA scenario it will be probably impossible to detect at the LHC any deviation from the SM predictions. In the SMcontext the size of the electroweak correctionswithout the hard emis- sion seems to be very large, but we expect that the total effect should be con- siderably reduced adding the hard emission part.
Nella tesi vengono riportati e discussi i risultati per il calcolo completo delle correzioni radiative elettrodeboli ad un loop per i due processi dominanti nella produzioe di quark Top singoli al Large Hadron Collider: la produzione associata tW e il processo di "canale t". Le correzioni ad un loop sono calcolate sia nelModello Standard (SM) che nella sua estensione supersimmetrica minimale (MSSM, assumendo uno scenario di mSUGRA); si è quindi analizzato l’effetto delle correzioni su varie osservabili fisiche, tentando di comprendere se siano riscontrabili deviazioni misurabili dalle predizioni del Modello Standard. La produzione di quark Top singoli costituisce la principale fonte di informzioni riguardo le interazioni deboli del Top e per lo studio e la comprensione della rottura della simmetria elettrodebole. Inoltre ai collider adronici la produzione di quark Top singoli costituisce l’unico processo che permette una misura diretta dell’elemento Vtb della matrice CKM, costituendo dunque un test fondamentale per la struttua del Modello Standard. Per la produzione associata tW si presenta il calcolo completo dell’effetto elettrodebole ad un loop, includendo poi l’effetto dell’emissione di fotoni duri; si combinano dunque i nostri risultati con i risultati (noti in letteratura) per le correzioni di QCD e QCD supersimmetrica, fornendo una descrizione completa ad un loop del processo. Abbiamo concentrato il nostro interesse su paticolari osservabili dette "rate parziali", con speciale attenzione alla regione di bassemasse invarianti: in data regione, tenendo conto delle correzioni di QCD supersimmetrica, il contributo genuinamente supersimmetrico dell’effetto ad un loop raggiunge il 10%, costituendo una deviazione potenzialmente osservabile. L’analisi del canale t è limitata alla sola componente elettrodebole (con l’aggiunta dell’emissione di fotini "soft", in modo da ottenere un risultao IR-finito): le correzioni ad un loop elettrodeboli per questo processo si sno rivelate meno sensibili alla presenza di eventuali particelle supersimmetriche; questa conclusione è comune nei quatro scenari mSUGRA analizzati. Considerando inoltre che l’effetto della QCD supersimmetrica è piccolo, si può concludere che sarà verosimilmente impossibile osservare deviazioni dalle predizioni SM. Nel Modello Standard le correzioni dovute alla parte elettrodebole sembrano numericamente molto significative, ma ci può aspettare una drastica riduzione di tale effetto una volta aggiunta l’emissione di fotoni reali "hard".

Abstract:
2007/2008
The thesis is devoted to the analysis of electroweak one-loop corrections to processes of production of scalar quarks of the third family at the Large Hadron Collider (LHC) in the context of the minimal supersymmetric extension of the Standard Model (MSSM). Third family squarks are are predicted to be among the lightest supersymmetric particles, hence they could be among the first signals of new physics to be detected at the LHC. Moreover, a very light stop (with a mass of the same order of the top mass) might play a relevant role within a cosmological model of electroweak baryogenesis. A precise analysis of one-loop corrections to processes of production of stop and sbottom particles and the determination of theoretical predictions to be tested against LHC data are therefore mandatory to understand the properties of these particles. The EW NLO corrections to the most meaningful observables related to these processes (differential and total cross sections) have been calculated and the dependence on supersymmetric parameters of the considered observables has been analysed. The considered processes are: 1) PP -> gg -> stop-antistop (sbottom-antisbottom); 2) PP-> bg -> stop-chargino. In both cases the analysis has been performed within various mSUGRA scenarios. For this purpose three C++ codes which exploit Monte Carlo techniques for the integration of cross sections have been developed. For the stop-antistop production case the diagonal production shows a total cross section of the order of 10 picobarns in some scenarios which predict a light stop; electroweak corrections, however, are of the order of few percent for every scenario considered; through the definition of the partial rates it is possible to obtain correction near to 10% in the high invariant mass region. The analysis of the dependence of one-loop corrections on mSUGRA parameters has been performed and it has been verified that the dependence is quite mild (variations up to 4%). In the case of sbottom production the total cross sections are generally smaller than 1pb and the one-loop corrections are not very sizable. As far as the parametric dependence is concerned, for diagonal production of light sbottom an interesting dependence on the parameter tg(beta) has been found in a particular scenario. For the stop-chargino production process the total cross sections are of the order of the picobarn in scenarios where stop and charginos are not too massive. The one-loop corrections are of the order of few percent and, due to the small cross sections in the considered scenarios, they are unfortunaltely quite difficult to observe at the LHC; the analysis through the partial rates predicts higher corrections, though difficult to detect. Due to these results, the parametric analysis has been performed at tree level, where the observables depend on a limited number of supersymmetric parameters: the strongest dependence has been found to be on the stop mixing angle and on the supersymmetric parameter mu. The analysis of stop production processes within scenarios of electroweak baryogenesis has been performed in both cases. For the case of diagonal production of light stop-antistop pairs, the electroweak one-loop effect on the total cross section has been found to be quite mild. Due to the small stop mass the total cross section is however of the order of 10pb. Therefore, through the analysis of partial rate it is possible to predict effects of the order of 10% with a still detectable cross section. In the stop-chargino case, the total cross section has been found to be smaller than 1pb even in the lightest configuration, and the one-loop correction is 2%.
La presente tesi consiste nell'analisi delle correzioni elettrodeboli a 1 loop di alcuni processi di produzione di quark scalari della terza famiglia al Large Hadron Collider nell'ambito dell'estensione supersimmetrica minimale del Modello Standard (MSSM). Gli squark della terza famiglia sono particolarmente importanti perché si prevede che siano fra le particelle supersimmetriche più leggere, e per questo motivo potrebbero essere fra i primi segnali di nuova fisica ad essere osservati all'LHC. Inoltre, uno stop particolarmente leggero (con una massa dello stesso ordine di quella del top) potrebbe giocare un ruolo rilevante nell'ambito di un modello cosmologico di bariogenesi elettrodebole. Una precisa analisi delle correzioni a 1 loop dei processi di produzione di stop e sbottom con la determinazione di previsioni teoriche da verificare sperimentalmente ad LHC è quindi fondamentale per cercare di comprendere le proprietà di queste particelle. In questa tesi vengono calcolate le correzioni sui principali osservabili legati a questi processi (sezioni d'urto differenziali e totali) e viene analizzata la dipendenza dai parametri supersimmetrici degli osservabili considerati. I processi analizzati sono: 1) PP -> gg -> stop-antistop (sbottom-antisbottom); 2) PP -> bg -> stop-chargino. In entrambi i casi l'analisi è stata effettuata nel contesto di diversi scenari mSUGRA. Sono stati sviluppati per questo scopo tre codici in C++ che si avvalgono di tecniche di Monte Carlo per l'integrazione delle sezioni d'urto. Nel caso del processo di produzione di stop, si è verificato che per alcuni scenari che prevedono uno stop leggero, la produzione diagonale ha una sezione d'urto totale dell'ordine della decina di picobarn; le correzioni elettrodeboli però sono dell'ordine di qualche punto percentuale per tutti gli scenari considerati; tramite la definizione delle cosiddette rate parziali è possibile ottenere correzioni vicine al 10% nella regione di alte masse invarianti. E' stata poi eseguita un'analisi di come gli effetti a un loop dipendono dai parametri mSUGRA, verificando che la dipendenza è poco apprezzabile (variazioni del 4%). Nel caso di produzione di sbottom le sezioni d'urto sono generalmente inferiori al picobarn e le correzioni a 1 loop rimangono abbastanza limitate. Per quanto riguarda la dipendenza parametrica, per produzione diagonale di sbottom leggeri c'è una interessante dipendenza dal parametro tg(beta) in un particolare scenario supersimmetrico. Nel caso del processo di produzione di stop-chargino la sezione d'urto è dell'ordine del picobarn nei casi che prevedono stop e chargini non eccessivamente massivi. Anche in questo caso le correzioni a 1 loop sono di qualche punto percentuale, difficilmente visibili a LHC a causa delle basse sezioni d'urto negli scenari considerati; l'analisi delle rate parziale consente di ottenere correzioni maggiori, ma difficilmente osservabili. A causa della scarsa visibilità del processo, l'analisi parametrica è stata effettuata a livello albero, dove gli osservabili dipendono da un numero limitato di parametri supersimmetrici: la dipendenza maggiore risulta essere per l'angolo di mixing dello stop e dal parametro supersimmetrico mu. Per quanto riguarda l'analisi dei processi di produzione di stop nell'ambito di scenari di bariogenesi elettrodebole, nel caso di produzione diagonale di stop leggeri, l'effetto a 1 loop è scarso, ma data la piccola massa dello stop che determina una sezione d'urto dell'ordine della decina di picobarn, l'analisi della rate parziale permette di prevedere effetti dell'ordine del 10%. Nel caso di stop-chargino la sezione d'urto risulta essere inferiore al picobarn anche nella configurazione più leggera e la correzione a 1 loop è del 2%.

Il bosone di Higgs il tassello mancante del Modello Standard: predetto da Peter Higgs negli anni sessanta, non ancora stato osservato sperimental- mente. Il Large Hadron Collider stato costruito con questo obiettivo in mente, assieme a molti altri. Uno dei processi pi interessanti per la pro- duzione di Higgs Supersimmetrico bg -> bH0 ( A0, h0). La natura dell'accoppiamento Yukawa nel MSSM lo rende predominate per alti valori di tan(beta) . In questa tesi vengono calcolate le correzioni elettrodeboli ad un loop alla sezione d'urto del processo nel MSSM, e viene mostrato come esse possano essere molto rilevanti per alcune regioni dello spazio dei parametri. Viene anche mostrato come i risultati siano indipendenti dalla scelta dello schema di rinormalizzazione tra DCPR and DR, ed anche come la consueta Improved Born Approximation non riproduca accuratamente i risultati ad un loop, mentre una diversa possibile approssimazione, la Reduced Vertex Approximation, in migliore accordo con il calcolo completo. Viene quindi eff ettuato un confronto con i risultati per un Two Higgs Doublet Modle, e viene mostrato come la di erenza con i risultati nel MSSM sia rilevante ad un loop, rendendo lo studio di questo processo una possibile via per discriminare tra i due modelli.
The Higgs particle is the missing piece of the Standard Model picture: pre- dicted by Peter Higgs in the late sixties, it has yet to be observed in a collider. The Large Hadron Collider has been built with this goal in mind, among many others. A very important channel to look at for SUSY Higgs production is bg -> bH0 (A0, h0). The nature of the MSSM Yukawa couplings make it dominant for high Values of tan(beta) . In my work I calculate the electroweak one loop corrections to the cross section of the process' cross section in the MSSM, and show that they can be very relevant for some regions of the parameters' space. It is also shown how the results obey a nice scheme independence at one loop for the two renormalization schemes DCPR and DR, as well as how the usual Improved Born Approximation fails in this case to reproduce the one loop results accurately, while a di fferent suggested Reduced Vertex Approximation is in better agreement with the full calculation. I then proceed to make a comparison with the results for a Two Higgs Doublets Model, and show that the di fference with the MSSM are big at the one loop level, such that this process could provide a way to discriminate between the two models.

Abstract:
With the advent of the Large Hadron Collider, we are in a new era in Particle Physics, in which unprecedented energy scales can be probed. Although it is a discovery machine, it has already been shown to be able to produce experimental precisions at the percent level, and so our theoretical calculations must match that, which requires (at least) calculations to next-to-leading order (NLO). In this thesis, we explain and develop new techniques for the evaluation of one-loop integrals, which have historically been the bottleneck in NLO calculations. After introducing Quantum Field Theory and NLO calculations, we explain the process of tensor reduction and the golem95 method for avoiding its numerical instabilities. We follow this by discussing the techniques used to improve the stability of a library of scalar integrals (for two- and three-point integrals), and then we discuss the extension of the golem95 library to include complex internal masses, along with the reasons for doing so. We then bring together the GoSam project with the event generator Sherpa, in order to calculate the process pp -> e+e−μ+μ− by diboson production to NLO, including the (formally higher order) loop-induced process with gluons in the initial state.

Abstract:
The linear sigma model and its extension, Quantum Hadro-dynamics 3 (QHD-III) are discussed. QHD-III is a gauge-invariant model of the strong interaction based on the linear sigma model, which is made locally invariant under SU(2)L x SU(2)R. Parity conservation is imposed. The gauge bosons rho and a1 are made massive via a Higgs mechanism as in the standard model. The low-energy symmetries of QCD, the ability to evaluate corrections coming from meson loops and the derivation of unambiguous conserved currents is used to motivate QHD-III. A renormalized pipi scattering amplitude to 1-loop using Feynman diagrams in the linear sigma-model is derived. The renormalized corrections due to vector boson exchange are also calculated in QHD-III and explicitly shown to be negligible when their masses become large. The pion decay constant to 1-loop is also calculated and discussed. The gauge invariance of the theory is analyzed and exploited to identify the physical pion and to considerably simplify the QHD-III lagrangian. The 1-loop effective action of the linear sigma model is derived and its predictions are shown to be identical to the amplitudes calculated using Feynman diagrams. The 1-loop effective action of QHD-III is discussed and shown to provide an explicit proof of the decoupling theorem.

Abstract:
Le sujet de ma thèse recouvre deux aspects. En premier lieu, I'objectif était d'étudier et d'améliorer les méthodes de calcul à une boucle pour les corrections radiatives (CR) dans le cadre des théories de champs perturbatives. En second lieu, I'objectif était d'appliquer ces techniques pour calculer les effets dominants des CR électrofaibles au processus important de production de Higgs associé à deux quarks bottom au LHC du CERN. L'étude concerne Ie Higgs du Modèle Standard (MS). Le premier objectif est d'importance plutôt théorique. Bien que la méthode générale pour Ie calcul à une boucle des CR dans Ie MS soit, en principe, bien compris par Ie biais de la renormalisation, il y a un certain nombre de difficultés techniques. Celles-ci sont liées aux intégrales de boucle. Pour les processus avec plus de 4 particules externes, les expressions d'amplitude obtenues en utilisant la méthode d'analyse sont extrêmement lourdes et très difficiles à manipuler. Dans cette thèse, nous avons étudié ce problème et réalisé que tout Ie calcul peut être facilement optimisé si I'on utilise la méthode des amplitudes d'hélicité. Un autre problème est lié aux propriétés analytiques des intégrales scalaires. Une partie importante de cette thèse est consacrée à ce problème et a I'étude des équations de Landau. Nous avons trouvé des effets significatifs en raison de singularités de Landau dans Ie processus pp → b anti-b Higgs au LHC. Le deuxième objectif est d'ordre pratique avec des conséquences expérimentales. On peut résumer les résultats obtenus dans cette thèse comme suit. Si la masse du Higgs est d'environ 120GeV, la correction au premier ordre dominant est petite de I'ordre d'environ - 4%. Si la masse de Higgs est d'environ 160GeV, seuil de production d'une paire de W par Ie Higgs, les corrections électrofaible bénéficient du couplage fort du Yukawa du top et sont amplifiées par la singularité de Landau conduisant à une importante correction d'environ 50%
The aim of this thesis is twofold. First, to study methods to calculate one-loop corrections in the context of perturbative theories. Second, to apply those methods to calculate the leading electroweak (EW) corrections to the important process of Higgs production associated with two bottom quarks at the CERN Large Hadron Collider (LHC). Our study is restricted to the Standard Model (SM). The first aim is of theoretical importance. Though the general method to calculate one- loop corrections in the SM is, in principle, well understood by means of renormalisation, it presents a number of technical difficulties. They are all related to loop integrals. The analytical method making use of various techniques to reduce all the tensorial integrals in terms of a basis of scalar integrals is most widely used nowadays. A problem with this method is that for processes with more than 4 external particles the amplitude expressions are extremely cumbersome and very difficult to handle even with powerful computers. In this thesis, we have studied this problem and realised that the whole calculation can be easily optimised if one uses the helicity amplitude method. Another general problem is related to the analytic properties of the scalar loop integrals. An important part of this thesis is devoted to studying this by using Landau equations. We found significant effects due to Landau singularities in the process pp → b anti-b H at the LHC. The second aim is of experimental importance. This process is important to understand the bottom-Higgs Yukawa coupling. The result obtained in this thesis is the following. If the Higgs mass is about 120GeV then the next-to-leading order correction is small, about - 4%. If the Higgs mass is about 163GeV then the EW correction is strongly enhanced by the Landau singularities, leading to a significant correction of about 50%. This important phenomenon is carefully studied in this thesis

Abstract:
The heavy quark effective theory (HQET) and the heavy quark expansion (HQE) have developed into the standard tools in heavy-flavour physics. The lectures in this chapter introduce the basics of the approach and illustrates the methods by discussing some of their phenomenological applications. The chapter covers construction of the HQET Lagrangian, symmetries of HQET, HQET at one loop, and HQET applications to phenomenology. It also discusses HQE inclusive decays, operator product expansion (OPE), tree-level results, HQE parameters, QCD corrections, and end-point regions. It concludes by reiterating the enormous impact that both HQET and the HQE have had on particle physics phenomenology.
