Measurement of the direct CP violating charge asymmetry in $B^{\pm }\to {\mu }^{\pm }{\nu }_{\mu }{D}^0$ decays

Abstract

We present the first measurement of the CP violating charge asymmetry in $B^{\pm }\to {\mu }^{\pm }{\nu }_{\mu }{D}^0$ 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 $A^{\mu D^0}=\left[-0.14\pm 0.20\right]\%$, which is consistent with standard model predictions.
