Abstract
We present the first measurement of the

violating charge asymmetry in
B

D

decays using the full Run II integrated luminosity of
10.4

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

D

, which is consistent with standard model predictions.
