Measurement of CP violation in B⁰ → D⁺ D⁻ decays
- Abstract:
-
The CP violation observables S and C in the decay channel B⁰ → D⁺ D⁻ are determined from a sample of proton-proton collisions at centre-of-mass energies of 7 and 8 TeV, collected by the LHCb experiment and corresponding to an integrated luminosity of 3 fb^-1. The observable S describes CP violation in the interference between mixing and the decay amplitude, and C parametrizes direct CP violation in the decay. The following values are obtained from a flavour-tagged, decay-time-dependent analysis:
S = -0.54+0:17-0:16 (stat) ± 0:05 (syst) ;
C = 0:26+0:18-0:17 (stat) ± 0:02 (syst) :
These values constrain higher-order Standard Model corrections to be small
