.Asymmetries in the time-dependent rates of singly Cabibbo-suppressed D0K+K- and D0+- decays are measured in pp collision data sample collected with the LHCb detector during LHC Run 1, corresponding to an integrated luminosity of 3 fb(-1). The asymmetries in effective decay widths between D-0 and D0 decays, sensitive to indirect CP violation, are measured. These measurements show no evidence for CP violation and improve on the precision of the previous best measurements by nearly a factor of two.
