Implications of the measurement of the B0s Bbar0s massdifference

PDF Version Also Available for Download.

Description

We analyze the significant new model independent constraints on extensions of the standard model (SM) that follow from the recent measurements of the B{sup 0}{sub s} {bar B}{sup 0}{sub s} mass difference. The time-dependent CP asymmetry in B{sub s} {yields} {psi}{phi}, S{sub {psi}{phi}}, will be measured with good precision in the first year of 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 B{sub s} decay, A{sup s}{sub SL}, is also important to constrain these frameworks, and could give further clues to our ... continued below

Description

We analyze the significant new model independent constraints on extensions of the standard model (SM) that follow from the recent measurements of the B{sup 0}{sub s} {bar B}{sup 0}{sub s} mass difference. The time-dependent CP asymmetry in B{sub s} {yields} {psi}{phi}, S{sub {psi}{phi}}, will be measured with good precision in the first year of 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 B{sub s} decay, A{sup s}{sub SL}, 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{sub {psi}{phi}} and A{sup s}{sub SL} in a very broad class of new physics models.
