# Search for CP violation in Bs0→μ+Ds-X decays in pp̅ collisions at √s=1.96  TeV

Abstract : We have performed a search for CP violation in a sample of semileptonic Bs decays corresponding to approximately 5 inverse femtobarns of data collected by the D0 detector in Run II at the Fermilab Tevatron Collider. A time-dependent fit to the distributions of the Bs candidates yields the flavor-specific asymmetry $a_{fs}^{s}=[-1.7\pm 9.1\mathrm{(stat)}^{+1.2}_{-2.3}\mathrm{(syst)}]\times 10^{-3}$. This is the most precise measurement to date of this CP violation parameter.
