Abstract

The first measurement of the CP asymmetry of the decay rate (ACP) and the CP average (SigmaA_{FB}) and CP asymmetry (Delta A_{FB}) of the forward-backward asymmetry in the muon system of Lambdac+ -> pmu+mu- decays is reported. The measurement is performed using a data sample of proton-proton collisions, recorded by the LHCb experiment from 2016 to 2018 at a center-of-mass energy of 13 TeV, which corresponds to an integrated luminosity of 5.4 fb-1.
