Description
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 \epsilon_K and the
updated lattice average for B_K. Generalizing 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 result in this
analysis is the hint of NP found in the B_s-\bar B_s mixing at the level of more
than 2 sigma.
