Measurement of CP Violation in B<sub>s</sub> → J/ψ φ Decays at CDF
(University of Warwick)
The B0s mixing phase βs is a key probe of physics beyond the standard model (SM). The first Tevatron measurements hinted at a ~2σ departure from the SM expectations. We present a new analysis using B0s → J/ψ φ decays reconstructed in 5.2 fb-1 of data collected by CDF detector, where tightened bounds on the mixing phase are obtained along with an improved measurement of the decay-width difference ΔΓs and of B0s.
