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 …
