• Аннотация: Time-dependent CP asymmetries in the decay rates of the singly Cabibbo-suppressed decays D0→K−K+ and D0→π−π+ are measured in pp collision data corresponding to an integrated luminosity of 3.0 fb−1 collected by the LHCb experiment. The D0 mesons are produced in semileptonic b -hadron decays, where the charge of the accompanying muon is used to determine the initial state as D0 or D¯¯¯0 . The asymmetries in effective lifetimes between D0 and D¯¯¯0 decays, which are sensitive to indirect CP violation, are determined to be AΓ(K−K+)=(−0.134±0.077+0.026−0.034)%,AΓ(π−π+)=(−0.092±0.145+0.025−0.033)%, where the first uncertainties are statistical and the second systematic. This result is in agreement with previous measurements and with the hypothesis of no indirect CP violation in D0 decays.
