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−→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 A^C^P(B⁻→ D⁻D⁰). Neither result shows evidence of CP violation.
