Measurement of CP violation in B0 → Dπ± decays

LHCb Collaboration

Research output: Contribution to journalArticlepeer-review


A measurement of the CP asymmetries Sf and Sf¯ in B0 → Dπ± decays is reported. The decays are reconstructed in a dataset collected with the LHCb experiment in proton-proton collisions at centre-of-mass energies of 7 and 8 TeV and corresponding to an integrated luminosity of 3.0 fb1. The CP asymmetries are measured to be Sf = 0.058 ± 0.020 (stat) ± 0.011 (syst) and Sf¯ = 0.038 ± 0.020 (stat) ± 0.007 (syst). These results are in agreement with, and more precise than, previous determinations. They are used to constrain angles of the unitarity triangle, | sin (2β + γ) | and γ, to intervals that are consistent with the current world-average values.
