Measurement of the direct C P violating charge asymmetry in B±→μ±νμD0 decays
Abstract
We present the first measurement of the C P violating charge asymmetry in B±→μ±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 Aμ D0=[-0.14 ±0.20 ] % , which is consistent with standard model predictions.
