Measurement of the helicity suppressed ratio of charged kaon leptonic decay rates BR(K -> e nu)/BR(K -> mu nu) has long been considered as an excellent test of lepton universality and the Standard Model (SM) description of weak interactions. It was realised recently that the suppression of the SM contribution might enhance the sensitivity to SUSY-induced effects to an experimentally...

A review of all relevant experimental and theoretical inputs from the contributing domains of electroweak interaction are provided together with numerical and graphical constraints on the CKM parameters and predictions of related physical observables. We...

Parallel Session Talk
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...
