Charge Asymmetries in Semileptonic B Decays
Abstract
I present measurements made by the D0 collaboration of the time-integrated flavor-specific semileptonic charge asymmetry in the decays of the Bs and Bd mesons that have undergone flavor mixing, asls and asld, using 10.4 fb^-1 of proton-antiproton collisions collected by the D0 detector during Run II at the Fermilab Tevatron Collider. The results are asls = [-1.12 \pm 0.74 (stat) \pm 0.17 (syst) ]% and asld = [0.68 \pm 0.45 (stat.) \pm 0.14 (syst.)]% which are the two most precise published results and are in agreement with standard model predictions. These results are combined with the like-sign dimuon charge asymmetry, aslb, and recent preliminary results from the LHCb and BaBar experiments to obtain new world averages.
