dc.description.abstract We analyse present constraints on the SM parameter space and derive, in a model independent way, various bounds on New Physics contributions to B-d(0)-(B) over bar (0)(d) and B-s(0)-(B) over bar (0)(s) mixings. Our analyses include information on a large set of asymmetries, leading to the measurement of the CKM phases gamma and (beta) over bar, as well as recent data from D0 and CDF related to the B-s(0)-(B) over bar (0)(s) system such as the measurement of Delta MBs, A and Delta Gamma(CP)(S). We examine in detail several observables such as the asymmetries A(sl)(d), A, the width differences Delta Gamma(d) and Delta Gamma(CP)(S) and discuss the role they play in establishing the limits on New Physics. The present data clearly favour the SM, with the New Physics favoured region placed around the SM solution. A New Physics solution significantly different from the SM is still allowed, albeit quite disfavoured (2.6% probability). We analyse the presently available indirect knowledge on the phase (chi) over bar entering in B-s(0)-B-s(0) mixing and study the impact of a future measurement of (chi) over bar to be achieved at LHC, through the measurement of the time-dependent CP asymmetry in B-s -> J/Psi theta decays.
