dc.description.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 A(J/ψK)=[0.59±0.37]%, which is the most precise measurement to date, and A(J/ψπ)=[−4.2±4.5]%. Both measurements are consistent with standard model predictions. | |
