Abstract
Time-integrated CP asymmetries in D0 decays to the final states K−K+ and π−π+ are measured using proton-proton collisions corresponding to 3fb−1 of integrated luminosity collected at centre-of-mass energies of 7TeV and 8TeV. The D0 mesons are produced in semileptonic b-hadron decays, where the charge of the accompanying muon is used to determine the initial flavour of the charm meson.File in questo prodotto:
