Search for New Physics in the B0s mixing phase at CDF

Abstract

The Collider Detector at Fermilab (CDF) experiment performed the first measurement of the time-evolution of flavor-tagged B0s->J/psiphi decays, which probes mixing-induced CP-violation in the B0s sector. Any sizable deviation from zero of the phase beta_s, accessible through interference of the bbar\to cbar c sbar quark-level process accompanied or not by B0s-aB0s mixing, would be unambiguous indication of physics beyond the Standard Model. I report CDF results obtained in 1.35/fb, a recent extension to a larger dataset corresponding to 2.8/fb, and future projections.
