Abstract

We present a measurement of the direct CP-violating charge asymmetry in B± mesons decaying to J/ψK± and J/ψπ± where J/ψ decays to μ+μ -, using the full run II data set of 10.4 fb-1 of proton-antiproton collisions collected using the D0 detector at the Fermilab Tevatron Collider. A difference in the yield of B- and B+ mesons in these decays is found by fitting to the difference between their reconstructed invariant mass distributions resulting in asymmetries of AJ /ψK=[0.59±0.37]%, which is the most precise measurement to date, and AJ/ψπ=[-4.2±4.5]%. Both measurements are consistent with standard model predictions.
