Hints of New Physics in b → s Transitions
Achille Stocchi (LAL- Université de Paris Sud/Orsay)
Seminar Room 3, 15:00
Combining all the available measurements on the Bs mixing, we have
found that the corresponding phase deviates at about 2.5σ with respect to the
one predicted by the Standard Model. No single measurement has a statistical significance
greater than 2σ and all the measurements are in good agreement.
In this seminar we will discuss in details these measurements and in particular the
most recent ones on Bs→J/ψ φ performed 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 → d and b- → d
transitions. Finally we present perspectives at future facilities for precise tests
both in b → s and in b →d sectors.
