Testo completoThough very successful in explaining a wide variety of particle physics phenomena, the Standard Model (SM) leaves unexplained some properties of nature. Here we focus on the different behaviours of left- and right-handed chiralities, or in other words the violation of parity symmetry. A possible and somewhat natural avenue to explain this feature is to embed the SM into a more symmetric framework, which treats the chiralities on equal footing. This class of models, the Left-Right (LR) Models, introduces new gauge interactions that couple preferentially to right-handed fields. Then, at an energy scale high enough, LR symmetry is spontaneously broken through the Brout-Englert-Higgs (BEH) mechanism, thus giving origin to the SM and to parity violating phenomena. The specific way in which the BEH mechanism operates in LR Models can be probed by EW Precision Observables, consisting of quantities that have been very accurately measured, serving as a first test of consistency for extensions of the SM in the EW sector. We revisit a simple realization of LR Models containing doublet scalars, and consider the phenomenological study of this doublet scenario in order to test the viability and structure of the LR Models. In particular, there is a rich phenomenology associated to the new gauge bosons W’ et Z’ introduced by LR Models, such as new sources of CP violation beyond the one of the SM. Moreover, the extended neutral scalar sector introduces Flavour Changing Neutral Couplings (FCNC) at tree level, which are strongly suppressed in the SM where they arrive first at one loop. FCNCs typically lead to extremely powerful constraints since they contribute to meson-mixing processes, and therefore deserve close attention. For this reason, we consider the calculation of short-distance QCD effects correcting the LR Model contributions to meson-mixing observables up to the Next-to-Leading Order (NLO), a precision required to set solid lower bounds on the LR Model scales. Finally, we combine in a global fit electroweak precision observables, direct searches for the new gauge bosons and meson oscillation observables in the simple case where the right-handed analogous of the CKM mixing-matrix is equal to the CKM matrix itself (a scenario called CKMfitter symmetry). The full set of the observables is combined by using the CKMfitter statistical framework, based on a frequentist analysis and a particular scheme for modeling theoretical uncertainties. We also discuss other possible modelings of theoretical uncertainties in a prospective study for future global flavour fits made by the CKMfitter Collaboration

Testo completoOne of the effective ways to search for signs of New Physics (NP) beyond the Standard Model (SM) is through the study of b→sℓ+ℓ− (ℓ is a lepton) transitions, which involve Flavour Changing Neutral Currents (FCNC) via box or loop diagrams. While the SM predicts that the photon is predominantly left-handed in b→sγ transitions, with a small right-handed component, the presence of New Physics (NP) could manifest as a more substantial right-handed current. LHCb has previously conducted an angular analysis on B→K*ee in the low dielectron mass region where the primary contributions to the loop processes arise from the coupling of a virtual photon to the dielectron pair. It has delivered the world's most accurate measurement of photon polarization in b→sγ transitions. The objective of my thesis is to conduct an angular analysis on the Bs→ϕe+e− decay channel in the low dielectron mass region, utilizing the complete LHCb dataset corresponding to an integrated luminosity of 9 fb-1 of proton-proton collisions. This analysis aims to provide a clean and novel measurement of photon polarization, marking the first instance of such an analysis with the Bs meson. Furthermore, it complements the previously established measurements in the B0 channel.The second aspect of my thesis involved the development of an online monitoring tool for use during Run 3 at LHCb. With the LHC transitioning to higher luminosity and generating larger data samples, real-time monitoring of physics variables becomes increasingly crucial. This automatic analysis tool is utilized to detect anomalies by conducting checks on data collected in real-time, ensuring the integrity and reliability of the experimental data

Testo completoHeavy quarks, namely c and b, at the RHIC energy scale are produced mainly in the early stages of the collision. Thus they are expected to be a good probe to study the _rst moments of the system formation. However the analysis of the spectra of non-photonic electrons, that comes form c and b semi-leptonic decays, shows suppression of the nuclear modi_cation factor for the large transverse momenta (pT) similar to the one measured for the light _avor hadrons, which contradicts the theoretical prediction. To understand this phenomenon a separate measurement of the c and b contribution to those spectra had to be carried out. This has already been done for the proton-proton collisions at 200 GeV. For this study in the STAR experiment a special technique, the electron_D0 azimuthal angular correlations has been developed. This thesis shows that the capabilities of the current setup of the STAR detector do not allow to perform this kind of measurement in the Gold Gold collisions at 200 GeV. Furthermore it shows that the application of this method in proton-proton collision at 500 GeV results in a dominant production of the b in comparison with c quark for the energy of non-photonic electron from the heavy _avor decay greater than 4. 3 GeV. The inclusive spectra of the charm particles (D0 and D*) has been measured by STAR in proton-proton minimum bias collisions in the range of pT up to 7 GeV/c. This thesis presents a new pioneering study on the D* measurement in High Tower dataset which allows to extend the spectra in pT up to 18 GeV/c in the protonproton system at 500 GeV. That range of the pT for D* meson has never been reached before on any system measured in STAR
