Implications of the measurement of the Bs(0)Bs(0) mass difference.
We analyze the significant new model independent constraints on extensions of the standard model (SM) that follow from the recent measurements of the Bs(0)Bs(0) mass difference. The time-dependent CP asymmetry in Bs-->psiphi, S(psiphi), will be measured with good precision in the first year of CERN Large Hadron Collider (LHC) data taking, which will further constrain the parameter space of many extensions of the SM, in particular, next-to-minimal flavor violation. The CP asymmetry in semileptonic Bs decay, ASL(s), is also important to constrain these frameworks, and could give further clues to our understanding the flavor sector in the LHC era. We point out a strong correlation between S(psiphi) and ASL(s) in a very broad class of new physics models.
