Abstract

We have performed a search for CP violation in a sample of Bs0μ+DsX decays corresponding to 5fb1 of proton-antiproton collisions collected by the D0 detector in Run II at the Fermilab Tevatron Collider. New physics in Bs0 mixing could contribute a significant CP violating weak phase, which would be observed as a difference in the decay-time distribution for Bs0B¯s0 oscillated states versus that for B¯s0Bs0. A fit to the decay-time distributions of the Bs0/B¯s0 candidates yields the flavor-specific asymmetry afss=[1.7±9.1(stat)1.5+1.4(syst)]×103, which excludes CP violation due to new physics within the experimental sensitivity.
