Abstract
A measurement of the decay time-dependent -violating asymmetry in decays is presented, along with measurements of the -odd triple-product asymmetries. In this decay channel, the -violating weak phase arises from the interference between mixing and the loop-induced decay amplitude. Using a sample of proton-proton collision data corresponding to an integrated luminosity of collected with the LHCb detector, a signal yield of approximately 4000 decays is obtained. The -violating phase is measured to be . The triple-product asymmetries are measured to be and . Results are consistent with the hypothesis of conservation.
