Abstract
AbstractTheCPasymmetry inB− → Ds−D0andB−→D−D0decays is measured using LHCb data corresponding to an integrated luminosity of 3.0 fb−1, collected inppcollisions at centre-of-mass energies of 7 and 8 TeV. The results are$$ {\mathcal{A}}^{CP}\left({B}^{-}\to {D}_s^{-}{D}^0\right)=\left(-0.4\pm 0.5\pm 0.5\right)\%\kern0.5em \mathrm{and}\kern0.5em {\mathcal{A}}^{CP}\left({B}^{-}\to {D}^{-}{D}^0\right)=\left(2.3\pm 2.7\pm 0.4\right)\% $$ACPB−→Ds−D0=−0.4±0.5±0.5%andACPB−→D−D0=2.3±2.7±0.4%, where the first uncertainties are statistical and the second systematic. This is the first measurement of$$ {\mathcal{A}}^{CP}\left({B}^{-}\to {D}_s^{-}{D}^0\right) $$ACPB−→Ds−D0and the most precise determination of$$ {\mathcal{A}}^{CP}\left({B}^{-}\to {D}^{-}{D}^0\right) $$ACPB−→D−D0. Neither result shows evidence ofCPviolation.
