Description
We present the first measurement of the CP violating charge asymmetry in B± → mu±νμD0 decays using the full Run II integrated luminosity of 10.4 fb-1 in proton-antiproton collisions collected with the D0 detector at the Fermilab Tevatron Collider. We measure a difference in the yield of B- and B+ mesons in these decays by fitting the reconstructed invariant mass distributions. This results in an asymmetry of AμD0) = [-0.14 ± 0.20] %, which is consistent with standard model predictions. (authors)
