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

Abstract : We present the update of the Unitarity Triangle (UT) analysis performed by the UTfit Collaboration within the Standard Model (SM) and beyond. Within the SM, combining the direct measurements on sides and angles, the UT turns out to be over-constrained in a consistent way, with some tension due to recently included contributions to the theoretical prediction of εK and the updated lattice average for BK. Generalising the UT analysis to investigate NP effects, constraints on b→s transitions are also included and both CKM and NP parameters are fitted simultaneously. The most interesting results on the b→s transitions come from the Bs−¯ Bs mixing and the di-muon charge asymmetry with updated results recently available from the Tevatron experiments. We observe a departure from the SM in the Bs sector.
