Description
The LHCb collaboration has recently released a number of new and updated measurements of the CP violating angles β and φs using the full 2011 and 2012 datasets. These CP violating parameters, which are sensitive to possible BSM physics, are observable in the interference between mixing and b->ccs decays of B and Bs mesons, respectively. LHCb has measured sin(2β) in an analysis of B -> J/ψ KS and multiple measurements of φs in analyses of Bs -> J/ψ φ, Bs -> J/ψ π π, and Bs -> Ds Ds. The effective angle φs is also measured in the rare decay Bs -> φ φ, which proceeds through a suppressed b->sss penguin diagram, and is thus also sensitive to new physics through the decay amplitude. Analyzing the interference between neutral meson mixing and decay necessitates a flavor-tagged lifetime analysis. This talk will present the latest results from LHCb on these channels.
