© 2018, The Author(s). 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 ACP(B−→Ds−D0)=(−0.4±0.5±0.5)%andACP(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−→Ds−D0) and the most precise determination of ACP(B−→ D−D0). Neither result shows evidence of CP violation.
