Abstract
The first measurements of the forward-backward asymmetry of the dimuon pair (), the triple-product asymmetry (), and the charge-parity-conjugation asymmetry (), in and decays are reported. They are performed using data from proton-proton collisions collected with the LHCb experiment from 2011 to 2016, corresponding to a total integrated luminosity of . The asymmetries are measured to be , , , , , , where the first uncertainty is statistical and the second systematic. The asymmetries are also measured as a function of the dimuon invariant mass. The results are consistent with the standard model predictions.
