The differential and total cross sections of the single gauge boson production in quasielastic high energy electron-photon scattering are obtained within the Standard Model in leading order and next-to-leading order of the perturbative theory. The contribution of divergent part of hard photon bremsstrahlung was included. The anomalous gauge boson coupling in the effective Lagrangian approach were studied. It is shown the analysis of neutral gauge couplings can be fully performed for two constants with different types of symmetries. Numerical analysis has been done. The best conditions were determined for registration of generated effects beyond the Standard Model.

We address the effect of an anomalous triple gauge boson couplings on a physical observable for the electroweak sector of the Standard Model, when the S U 2 L ⊗ U 1 Y symmetry is spontaneously broken by the Higgs mechanism to U 1 e m . Our calculation is done within the framework of the gauge-invariant, but path-dependent variable formalism is an alternative to the Wilson loop approach. Our result shows that the interaction energy is the sum of a Yukawa and a linear potential, leading to the confinement of static probe charges. The point we wish to emphasize, however, is that the anomalous triple gauge boson couplings ( Z γ γ ) contributes to the confinement for distances on the intranuclear scale.

Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Physics, 2001.
Includes bibliographical references (leaves 48-52).
W-Pair and Single-W production events are observed at LEP, the Large Electron Positron collider at CERN, using the L3 detector. All decay channels are considered, and data taken in the years 1998 and 1999, with electron-positron collision centre-of-mass energies from 189 GeV to 202 GeV are analysed. The integrated luminosity of the analysed data corresponds to approximately 400pb-1, and a total of approximately 5000 W-pair events and 100 single-W events are selected. The observed cross sections of these W production processes and the differential distributions of the event shapes are then used to measure the couplings of Wbosons with Z bosons and photons. Emphasis is placed on the unambiguous and efficient combination of the information from the different production and decay channels. For the couplings in the model in which gauge invariance is realised linearly, the following results are obtained ... where the errors shown are statistical, systematic and theoretical respectively. All results show consistency with expectations from the Standard Model.

Cette thèse présente le mesure des sections efficaces de production WW MS et la détermination des couplages triples (TGCs) correspondants en utilisant ces 4.7 fb⁻¹ de donnes 2011 de collision pp. Ces mesures permettent un test contraignant du secteur 'électrofaible non abélien SU(2) X U(1) du Modèle Standard; donnent l'opportunité de sonder la nouvelle physique `a travers les couplages triples anormaux de bosons de jauge (aTGCs) qui seront observés dans la distribution des variables cinématiques des WW produits ou de leurs produits de désintégration finaux dans le secteur de haute 'énergie; et permettent d'avoir une bonne compréhension du bruit de fond irréductible dans la recherche du boson de Higgs dans le canal de d'esint'egration H → W⁺W⁻.Ce travail de th`ese donne un base solide pour les mesures à venir de la production WW avec les ∼25 fb⁻¹ de luminosité intègré de donnes a 8 TeV prévue pour la fin 2012, qui conduiront vers une amélioration de la précision et des limites plus strictes sur les aTGCs
This thesis presents a measurement of the SM WW production cross section and the determination of the corresponding limits on anomalous triple gauge boson couplings (aTGCs), using the 2011 4.7 fb⁻¹ pp collisions data at 7 TeV collected in 2011. The measurement allows for a stringent test of the non-Abelian SU(2) X U(1) SM electroweak sector and probes new physics that could manifest itself through aTGCs that may alter the observed production cross section or kinematic distributions. This measurement also provides a good understanding of the irreducible background in searches for the Higgs boson through the H → W⁺W⁻ decay channel.This thesis work has laid a solid foundation for further measurements of the WW production with the ∼25 fb⁻¹ integrated luminosity 8 TeV recorded data expected by the end of 2012, which will further improve the precision and yield more stringent limits on the aTGCs

This thesis is a presentation of an analysis of the $ZZ\rightarrow 4\ell$ ($\ell = e,\mu$) process in proton-proton collisions with centre-of-mass energy $\sqrt{s}$ = 13 TeV at the LHC during 2015 and 2016 (a total integrated luminosity of 36.1 fb$^{-1}$), using the ATLAS detector. Candidate $ZZ \rightarrow 4\ell$ events are selected in the three decay channels, $4e$, $2e2\mu$ and $4\mu$. The cross section of the $ZZ\rightarrow 4\ell$ process is measured in four fiducial regions closely matching the detector acceptance: one for each decay channel ($4e$, $2e2\mu$ and $4\mu$) and one for the combination of all decay channels. The total cross section of $pp\rightarrow ZZ$ is measured in a phase-space in which both $Z$ bosons have a mass $m_{Z}$ in the range 66 GeV $ < m_{Z} < $ 116 GeV to be 16.5 $\pm 0.5$ (stat.) $\pm 0.4$ (syst.) $\pm 0.5$ (lumi.)$\,$ pb which is consistent with a next-to-next-to-leading-order prediction of $16.9^{+0.6}_{-0.5}$ pb. Observed event yields in four bins of transverse momentum are used to set 95{\%} CL$_{\text{s}}$ limits on four neutral triple gauge couplings ($f^{V}_{i}$, $V=Z,\gamma$, $i=4,5$) which parameterise an effective $ZZV$ vertex (assuming both $Z$ bosons are on shell). The obtained limits are of the order of $|f^{V}_{i}|<0.0017$.

Ohne ein Standard Modell Higgs werden Wechselwirkungen zwischen Eichbosonen stark bei hohen Energien. Jeder tri- und quadrilinare Eichboson-Vertex ist charakterisiert durch einen Satz von Kopplungen der schon bei niedrigeren Energien als der Skala für neue Physik von seiner Standardmodell- Erwartung abweichen sollte. Die genaue Messung der Eichbosonkopplungen gewährt daher Einblicke in den Mechanismus der elektroschwachen Symmetriebrechung und anomale Werte signalisieren neue Physik. Die Sensitivität der Messung der geladenen Eichboson Kopplungen an einem Photoncollider mit TESLA Parametern wurde studiert. Die betrachteten Prozesse sind ein- und zwei-W-Boson Produktion in Elektron-Photon und Photon-Photon Kollisionen bei einer Elektron-Elektron Energie von 500 GeV. Signal und Untergrund Ereignisse wurden im hadronischen Zerfallskanal analysiert und ein Satz von konsekutiven Schnitten wurde angewandt, die eine gute Effizienz und Reinheit des Signals ergaben. Die selektierten Ereignisse wurden durch kinematische Variablen beschrieben, die sensitiv sind auf anomale Kopplungen. Eine neue Methode wurde angewandt, um dies Winkelverteilungen in Anwesenheit von anomalen Kopplungen zu fitten. Dazu wurden die differentiellen Wirkungsquerschnitte in bis zu quadratischen Thermen in den Kopplungen entwickelt. Im Fit wurde diese Funktion benutzt, um die mehrdimensional gebinnten Verteilungen abhängig von den anomalen Kopplungen zu rewichten. Dabei wurde auch die Unsicherheit in der Normalisierung berücksichtigt. Außerdem wurden einige Quellen systematischer Fehler, z.B. durch die Strahlenergie, die W-Boson Masse und die Polarisationsmessung untersucht. Die erwarteten Fehler auf die Eichkopplungen bei einem Photon-Collider sind ca. zwei Größenordnungen kleiner als bei LEP und am Tevatron, so dass ein sehr präziser Test von Physik jenseits des Standardmodells möglich wird. Die Optimierung der Vorwärtsregion der Detektors reduziert den nieder- energetischen Untergrund auf ein tolerierbares Maß. Dies schafft die nötige saubere Umgebung für eine präzise Messung der Eichkopplungen.
In absence of the Standard Model (SM) Higgs boson the interaction among the gauge bosons becomes strong at high energies and influences the couplings between them. Each trilinear and quartic gauge boson vertex is characterised by a set of couplings which are expected to deviate from their SM values already at energies lower than the energy scale of the New Physics (NP). The precise measurement of gauge boson couplings can provide clues to the mechanism of the electroweak symmetry breaking and their anomalous values can be a sign of a NP effect beyond the SM. The sensitivity estimation of the measurement of charged trilinear gauge couplings (TGCs) at the Photon Collider based on TESLA parameters has been studied. The considered interactions are the single and double W boson production in electron-photon and photon-photon collisions (signals) at electron-electron centre-of-mass energy of 500 GeV. Signal and background events in the hadronic decay mode overlayed with the pileup, are simulated and analysed and a set of consecutive cuts is applied resulting in good signal efficiencies. The selected events are described with kinematical variables sensitive to TGCs. A new method has been applied to fit event angular distributions in the presence of anomalous TGCs expanding the dependence of the differential cross-section up to quadratic term in the TGCs. In the fit this expression is used to reweight the SM multi-dimensional binned distributions dependent on TGCs where also the uncertainty on the total normalisation is taken into account. Some sources of systematic errors are considered, as the beam energy, the W boson mass and the polarisation measurement. The estimated precisions of the TGC measurements at a photon collider are about one to two orders of magnitude higher than at LEP and Tevatron providing a measurement highly sensitive to the physics beyond the Standard Model. The optimisation of the forward region of the detector brings the amount of the low-energy background to the manageable level providing a clean environment for the TGC measurements at a photon collider with estimated precisions.
