B0−Bˉ0B^0 - \bar{B}^0 oscillations and measurements of ∣Vub∣/∣Vcb∣|V_{ub}|/|V_{cb}| at LEP

In this paper a review of the LEP analyses on $B^0 - \bar{B}^0$ oscillations and on the measurement of $|V_{ub}|/|V_{cb}|$ is presented . These measurements are of fundamental importance in constraining the $\rho$ and $\eta$ parameters of the CKM matrix. A review of the current status of the $V_{CKM}$ matrix determination is also given.Comment: Talk given at the "HQ98 Conference", Fermilab - Batavia (USA), October 10-12, 199

Determination of Unitarity Triangle parameters: where do we stand ?

In this note I review the current determination of the unitarity triangle parameters by using the theoretical and experimental information available in summer 2000.Comment: Invited talk given at the 7th International Conference on B-Physics at Hadron Machines- Beauty2000, Kibbutz Maagan, Israel, September 13-18, 200

Current Status of the CKM Matrix and the CP Violation

These lectures give an introduction and the current status of flavour physics in the quark sector, with special attention to the CKM matrix and CP violation. We describe the measurements which contribute to the determination of the CKM matrix elements and how, together with important theoretical developments, they have significantly improved our knowledge on the flavour sector of the Standard Model. These lectures are complemented by the seminar of U. Mallik (see these proceedings) which describes in more details the most recent CP-violating related measurements by the B-factories. The results presented are up-to-date till winter 2004.Comment: Lectures given at the Cargese School of Particle Physics and Cosmology - Cargese, August 4-16th, 200

Physics Opportunities at the Next Generation of Precision Flavor Physics

Starting with next-generation experiments, flavor physics fully enters the era of precision measurements. The focus shifts from testing the Standard Model to finding and characterizing new physics contributions. We review the opportunities offered by future flavor experiments, discussing the expected sensitivities of the most important measurements. We also present some examples of measurable deviations from the Standard Model in the flavor sector generated in a selection of new physics models, demonstrating the major contribution that precision flavor physics could give to the effort of going beyond the Standard Model.Comment: Posted with permission from the Annual Review of Nuclear and Particle Science, Volume 61. by Annual Reviews, http://www.annualreviews.or

Standard Model updates and new physics analysis with the Unitarity Triangle fit

We present here the update of the Unitarity Triangle (UT) analysis performed by the UTfit Collaboration within the Standard Model (SM) and beyond. Continuously updated flavour results contribute to improving the precision of several constraints and through the global fit of the CKM parameters and the SM predictions. We also extend the UT analysis to investigate new physics (NP) effects on $\Delta F=2$ processes. Finally, based on the NP constraints, we derive upper bounds on the coefficients of the most general $\Delta F=2$ effective Hamiltonian. These upper bounds can be translated into lower bounds on the scale of NP that contributes to these low-energy effective interactions.Comment: Proceedings of the 8th International Workshop on the CKM Unitarity Triangle (CKM 2014), Vienna, Austria, September 8-12, 201
