The time-dependent asymmetry in decays is measured using proton-proton collision data corresponding to an integrated luminosity of , collected with the LHCb detector at a center-of-mass energy of 13 TeV during the years 2015–2018. The -violation parameters for this process are determined to be and , where the first uncertainty is statistical and the second systematic. This constitutes the first observation of time-dependent violation in decays. Assuming approximate SU(3) flavor symmetry, these results are combined with the previous consistent LHCb measurement to set the most stringent constraint on the penguin contribution, , to the -violating phase in decays, yielding .more » « less
