Abstract: | Abstract: The CP asymmetry in B− → D− s D0 and B− → D−D0 decays is measured using LHCb data corresponding to an integrated luminosity of 3.0 fb−1 , collected in pp collisions at centre-of-mass energies of 7 and 8 TeV. The results are ACP (B− → D− s D0 ) = (−0.4 ± 0.5 ± 0.5)% and ACP (B− → D−D0 ) = (2.3 ± 2.7 ± 0.4)%, where the first uncertainties are statistical and the second systematic. This is the first measurement of ACP (B− → D− s D0 ) and the most precise determination of ACP (B− → D−D0 ). Neither result shows evidence of CP violation. |
