Measurement of direct CP asymmetry in B± → J/ K± decays produced in pp̅ collisions at √s = 1.96TeV

A measurement of direct CP asymmetry is performed using 6fb−1 of pp̄ collisions at √s = 1.96TeV from the CDF detector at the Fermi National Accelerator Laboratory. Approximately 80,000 B− → J/ K− (and charge conjugate) events were selected on the dimuon trigger and the yields were determined using a simultaneous mass and lifetime fit. After corrections, a measurement of ACP = 0.0034 ± 0.0043(stat.) ± 0.0060(syst.) is obtained, which is consistent with the SM prediction and previous measurements at DØ and the B factories.
