Texto completoWe present a search for physics beyond the standard model (SM) through a measurement of the violation of the charge-parity (CP) symmetry in two decays of the Bs meson using data collected by the Collider Detector at Fermilab (CDF) in proton-antiproton collisions at the center-of-mass energy of 1.96 Tev. We exploit the decays Bs->Jpsi (->mu mu) phi(-> KK) and Bs -> phi(-> KK) phi(-> KK), for which the SM accurately predicts very small or vanishing CP violation; both decay modes are very sensitive to new sources of CP violation expected in a broad class of SM extensions. We analyze the time-dependent CP asymmetry of the Bs->Jpsi phi decays collected in the full CDF Run II dataset for providing the final measurement of the Bs-antiBs mixing phase, 2*betas, and we present the first measurement of CP violation in Bs -> Phi Phi decays, through the determination of two time-integrated CP asymmetries, Av and Au, using an original method developed in this work. We find: -0.06< betas<0.30 at the 68% confidence level; Av=(-12.0 +/-6.4(stat) +/- 1.6(syst))%; and Au=(-0.7 +/-6.4(stat) +/- 1.8(syst))%. In addition, we provide measurements of the decay width difference between the light and heavy mass eigenstates of the Bs meson, DeltaGamma_s=0.068 +/- 0.026(stat) +/- 0.009(syst) ps^{-1}; and of their mean lifetime, tau_s=1.528 +/- 0.019(stat) +/- 0.009(syst) ps. All results are among the most precise determinations from a single experiment and exhibit an excellent agreement with the SM predictions. They have been published in two letters in Physical Review.

Texto completoStudies of charmonium properties and production mechanism started with the discovery of J/ψ meson. Since more than 40 years the charmonium production mechanism is still not entirely understood. Following the era of investigations at e⁺e⁻ machines, nowadays, charmonium states are copiously produced at hadron colliders, that allows systematic studies of their resonance parameters, production observables and decays. Despite large production rates, many charmonium states are barely studied due to the complications of their reconstruction against a large background level. The LHCb experiment provides a unique opportunity to study S-wave and P-wave charmonium states using their decays to hadrons. This allows measuring production observables of ηc and χc charmonium states. According to the theoretical formalism of Non-Relativistic QCD (NRQCD), the production observables of the same wave charmonium states are linked. Hence, the LHCb measurements provide a series of stringent tests of NRQCD. In the framework of this thesis, the first measurement of the ηc(1S) differential production cross-section at √s=13 TeV and the most precise to date single mass measurement are performed, where the ηc(1S)$ state is reconstructed via its decay to proton and antiproton. In addition, the production of the χc and ηc(2S) states in b-hadron decays is studied using decays to φφ. The obtained results are confronted with existing theory predictions. The original phenomenological analysis concludes that the description of charmonium prompt production and production in inclusive b-hadron decays in an entire range of transverse momentum remains a challenge

Texto completoWe present a study of the charmless Bs to phiphi decay performed with the CDFII detector at the Fermilab Tevatron Collider. Charmless Bs meson decays currently can be studied only at the Tevatron and represent a field still to be fully explored that offers additional ways to test our present theoretical understanding. The Bs to phiphi belongs to a particular class of these decays: the Bs meson decays into a pair of vector particle and the final state is self-conjugate. It can be used to measure the Bs decay width difference (Delta Gamma_s), CKM studies, and tests of decay polarization predictions.

Texto completoThe work presented has been accomplished in the framework of the LHCb experiment. The thesis is divided into two parts: development and commissioning of the Radiation Monitoring System (RMS) and study of the expected performances for the measurement of the radiative decay Bs→φγ. The online monitoring of the background related to the accelerator is mandatory for the safety of the detector and for high quality data taking. The Metal Foil Detector technology was chosen for the radiation online monitoring. It is characterized by a fast time response and is sensitive to irradiation range corresponding to the conditions expected for nominal LHCb operation. It is robust and yields a moderate amount of material. The readout system and its integration in the LHC architecture have been realized. The results obtained with the RMS are in agreement with those from other systems that measure accelerator backgrounds. It has been shown that the RMS is sensitive to the pp collisions and is able to detect unexpected increase in the radiation rate. The second part of the thesis is dedicated to the study of the expected performances for the measurement of the radiative decay Bs→φγ. The selection criteria optimization has been realized with a full Monte Carlo simulation of the detector. The signal events simulation has been complemented by the detailed background studies. In nominal operation conditions, about 9000 signal events are expected to be recorded, reconstructed and selected. The background level is estimated to be B/S < 2. 9@90% CL

Texto completoThis document presents studies of radiative decays of B0 and Bs mesons to orbitally excited states, produced in proton collisions at the Large Hadron Collider (LHC) of CERN (European Council for Nuclear Research). It takes place in the context of the search for new physics processes beyond the standard model of particle physics. The work is based on the data collected at the LHCb experiment during the Run 1(2011-2012) and the Run 2 (2015-2018) of the LHC, which corresponds to an integrated luminosity of about 8.7 fb−1. First, an optimised selection of the final states comprising of two charged tracks and a high energy photon is put in place, regrouping a large samples of B hadron radiative decays. Then, a mass model is fit to the data distribution, allowing to statistically subtract the background contributions in the data set.A first amplitude analysis is then developed to study the hadronic structure in the Bs → K+K−γ decay mode. Resulting from this analysis is the first observation of the Bs → f2j (1525)γ mode together with a relative branching ratio measurement:B(Bs → f2j γ) = (24.1 ± 0.9 (stat) +1.6 (syst) ± 0.6 (br)) × 10−2B(Bs → φγ) −0.8It is the second radiative decay mode observed for the Bs meson. A similar analysis is performed on the B0 → K±π∓γ mode, allowing a preliminary measurement of the relative branching ratio of B0 → K2∗(1430)γ:(B0 K∗0(1430)γ)B(B0 → K∗0(892)γ) = (36.4 ± 0.4 (stat) ± 1.3(BR))%However, a detailed systematics study is needed to assess its competitivity with previous measurements of this decay mode. Making use of a similar selection strategy, a preliminary study of B K0hhγ modes is also set up during the thesis to estimate the available statistics for these modes at LHCb, which are particularly interesting to measure the photon polarisation in the b sγ transition. This work will be the starting point of an analysis comprising the future data that will be collected during the Run 3 of the LHC
