Abstract

The decay-time-dependent CP asymmetry in B0→ D∗±D∓ decays is mea- sured using a data set corresponding to an integrated luminosity of 9 fb−1 recorded by the LHCb detector in proton-proton collisions at centre-of-mass energies of 7, 8 and 13 TeV. The CP parameters are measured asSD∗D=−0.861±0.077(stat)±0.019(syst),ΔSD∗D=0.019±0.075(stat)±0.012(syst),CD∗D=−0.059±0.092(stat)±0.020(syst),ΔCD∗D=−0.031±0.092(stat)±0.016(syst),AD∗D=0.008±0.014(stat)±0.006(syst). The analysis provides the most precise single measurement of CP violation in this decay channel to date. All parameters are consistent with their current world average values.
