The CP-violating weak phase [phi]s of the B0 s meson and the decay width difference [Delta][Gamma]s of the B0 s light and heavy mass eigenstates are measured with the CMS detector at the LHC using a data sample of B0 s 2!/[psi] [phi](1020) 2!æ +æ -K+K- decays. Our analysed data set corresponds to an integrated luminosity of 19.7 fb-1 collected in pp collisions at a centre-of-mass energy of 8 TeV. Additionally, a total of 49 200 reconstructed B0 s decays are used to extract the values of [phi]s and [Delta][Gamma]s by performing a time-dependent and flavourtagged angular analysis of the æ +æ -K+K- final state. The weak phase is measured to be [phi]s = -0.075 " 0.097 (stat) " 0.031 (syst) rad, and the decay width difference is [Delta][Gamma]s = 0.095 " 0.013 (stat) " 0.007 (syst) ps-1.

The CP violating phase [beta] j/[Psi][Phi]s is measured in decays of B0s → J/[Psi][Phi]. This measurement uses 5.2 fb-1 of data collected in √s = 1.96 TeV p$\bar{p}$ collisions at the Fermilab Tevatron with the CDF Run-II detector. CP violation in the Bs0-$\bar{B}$s0 system is predicted to be very small in the Standard Model. However, several theories beyond the Standard Model allow enhancements to this quantity by heavier, New Physics particles entering second order weak mixing box diagrams. Previous measurements have hinted at a deviation from the Standard Model expectation value for [beta]sJ/[Psi][Phi] with a significance of approximately 2[sigma]. The measurement described in this thesis uses the highest statistics sample available to date in the Bs0 → J/[Psi][Phi] decay channel, where J/[Psi] → [mu]+[mu]- and [Phi] → K+K-. Furthermore, it contains several improvements over previous analyses, such as enhanced signal selection, fully calibrated particle ID and flavour tagging, and the inclusion of an additional decay component in the likelihood function. The added decay component considers S-wave states of KK pairs in the Bs0 → J/[Psi] K+K- channel. The results are presented as 2-dimensional frequentist confidence regions for [beta]sJ/[Psi][Phi] and [Delta][Gamma] (the width difference between the Bs0 mass eigenstates), and as a confidence interval for [beta]sJ/[Psi][Phi] of [0.02,0.52] U [1.08, 1.55] at the 68% confidence level. The measurement of the CP violating phase obtained in this thesis is complemented by the world's most precise measurement of the lifetime [tau]s = 1.53 ± 0.025 (stat.) ± 0.012 (syst.) ps and decay width difference [Delta][Gamma] = 0.075 ± 0.035 (stat.) ± 0.01 (syst.) ps-1 of the Bs0 meson, with the assumption of no CP violation.

The B{sub s} meson is an interesting particle to study because a sizable mixing induced CP violation in the B{sub s} -- {bar B}{sub s} system would be an indication for physics beyond the Standard Model. In this paper we present a measurement of the lifetime difference [Delta][Gamma] between the B{sub s} mass eigenstates and the CP violating phase in the decay B{sub s} → J/[psi][phi]. In 1.7 fb−1 of data collected with the CDF II detector at the Tevatron p{bar p} collider we measure [Delta][Gamma] = 0.076{sup +0.059}{sub -0.063} (stat.) ±0.006 (syst.) ps−1, well consistent with the Standard Model prediction, and a mean B{sub s} lifetime of c{sub tau}{sub s} = 456 ± 13 (stat.) ± (syst.) [mu]m. We find no evidence for CP violation.

The authors discuss the results from the Tevatron experiments on mixing and CP violation in the B{sub s}°-{bar B}{sub s}° system, with particular emphasis to the updated measurements of the decay-width difference [Delta][Lambda]{sub s} and the first measurement of the CP-violating phase [beta]{sub s} using flavor tagging information. They also briefly review the charge asymmetry measurements in semileptonic B{sub s}° decays and in B{sup {+-}} → J/[psi]K{sup {+-}} decays.

A B0 s meson can oscillate into its anti-particle, the $ar{B}$0 s meson, before decaying. CP violation in this system is made possible by the presence of amplitudes from both mixed and unmixed B0 s meson decays. The CP violating phase ?s appears in the interference between the decay amplitudes. The quantity sin(2?s) is expected to be small in the standard model. Thus, measuring a large value for sin(2?s) would be an unequivocal sign of new physics participation in the B0 s mixing loop diagram. In this thesis, we present a latest measurement of sin(2?s), using 5.2 fb-1 of data collected at CDF from p$ar{p}$ collisions at a center of mass energy of √s=1.96 TeV. A time-dependent angular analysis, with the production flavor of the B0 s meson identified with flavor tagging methods, is used to extract sin(2?s) from 6̃500 B0 s→ J/?? decays. Other parameters of interest, such as the B0 s lifetime and the decay width difference between the heavy and light B0 s mass eigenstates are determined to high precision. Also, the effect of potential contributions to the final state from B0 s → J/?f0 and B0 s→ J/?K+K- decays is considered for the first time. We present 68% and 95% confidence regions in the ?s plane. The probability that the observed central value is a fluctuation of the data from the standard model expected value of ?s is calculated to be 44%. The observed confidence region shows better agreement with the standard model prediction than previous measurements.
