Search for direct CP violation in D0→h-h+ modes using semileptonic B decays

# metadata.dc.description.abstract[].value
A search for direct CP violation in D0 → h−h+ (where h = K or π ) is presented using data corresponding to an integrated luminosity of 1.0 fb−1 collected in 2011 by LHCb in pp collisions at a centre-of-mass energy of 7 TeV. The analysis uses D0 mesons produced in inclusive semileptonic b-hadron decays to the D0μX final state, where the charge of the accompanying muon is used to tag the flavour of the D0 meson. The difference in the CP-violating asymmetries between the two decay channels is measured to be ACP = ACP (K − K +) − ACP (π −π +) = (0.49 ± 0.30 (stat) ± 0.14 (syst))%.
