Abstract
With full 2011 LHC data analyzed, there is no indication for deviation from standard model in CP violating phase for B s→J/ψφ, nor in the forward-backward asymmetry for B0→K *0μ +μ -. Standard model sensitivity, however, has been reached for the B s→μ +μ - rate, and there may be some hint for a suppression. We illustrate that, if a suppressed B(B s→μ +μ -) bears out with 2012 data, it would imply a lower bound on the fourth generation quark mixing product |Vt′s*V t′b|. © 2012 American Physical Society.
