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 $$A^{\mu D^{0}} =\left[ -0.03 \pm 0.27 \right]\%$$, which is consistent with standard model predictions.
