Hints of New Physics in b-->s transitions

Achille Stocchi (LAL, Universite de Paris/Orsay)

Combining all the available measurements on the Bsmixing, we have found that the corresponding phase deviates at about 2.5σwith respect to the one predicted by the Standard Model. No single measurement has a statistical significance greater than 2σand all the measurements are in good agreement. In this seminar we will discuss in detail these measurements and in particular the most recent ones on Bs->J/ΨΦperformed by the CDF and D0 collaborations. We will also give the framework in which our global analysis is performed, showing the results obtained in other sectors corresponding to the s->dand b->dtransitions. Finally we present perspectives at future facilities for precise tests both in b->sthan in b->dsectors.
