  Title First Measurement of Time-Dependent CP Violation in the Flavor-Changing Neutral-Current Decay B0 → KS0μ+μ- Type Journal Article

  Abstract A flavor-tagged time-dependent analysis of B-0 -> K-S(0)mu(+)mu(-) decays is performed across the full dimuon mass range excluding the J/psi and psi(2S) resonance regions. The analysis uses proton-proton collision data collected by the LHCb experiment in 2011-2018 at center-of-mass energies of 7, 8, and 13 TeV, corresponding to an integrated luminosity of 9 fb(-1). The CP violation parameters are determined to be C = -0.13 +/- 0.32 +/- 0.04, S = +0.82 +/- 0.29 +/- 0.05, where the first uncertainties are statistical and the second are systematic. The results are consistent with the standard model prediction. This is the first experimental study of time-dependent CP violation in b -> sl(+)l(-)processes.
