We present the first measurement of the C P violating charge asymmetry in B ± → μ ± ν μ D 0 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 A μ D 0 = [ − 0.14 ± 0.20 ] % , which is consistent with standard model predictions.
