Search for CP violation in B-s(0) -} mu(+) D-s(-) X decays in p(p)over-bar collisions at root s=1.96 TeV
Original language description
We have performed a search for CP violation in a sample of B-s(0) -} mu+Ds-X decays corresponding to 5 fb(-1) of proton-antiproton collisions collected by the D0 detector in Run II at the Fermilab Tevatron Collider. New physics in B-s(0) mixing could contribute a significant CP violating weak phase, which would be observed as a difference in the decay-time distribution for B-s(0) -} (B) over bar (0)(s) oscillated states versus that for (B) over bar (0)(s) -} B-s(0). A fit to the decay-time distributionsof the B-s(0)/(B) over bar (0)(s) candidates yields the flavor-specific asymmetry as a(fs)(s) = [-1.7 +/- 9.1(stat)(-1.5)(+1.4)(syst) x 10(-3), which excludes CP violation due to new physics within the experimental sensitivity.
