Abstract

The CP asymmetry in B− → Ds− 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 A^CP(B− → Ds− D0) = (−0.4 ± 0.5 ± 0.5)% and A^CP(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 A^CP(B− → Ds− D0) and the most precise determination of A^CP(B− → D− D0). Neither result shows evidence of CP violation.
