A search for violation of the charge-parity ( ) symmetry in the decay is presented, with proton-proton collision data corresponding to an integrated luminosity of , collected at a center-of-mass energy of 13 TeV with the LHCb detector. A novel model-independent technique is used to compare the and phase-space distributions, with instrumental asymmetries subtracted using the decay as a control channel. The value for the hypothesis of conservation is 8.1%. The asymmetry observables and are also measured. These results show no evidence of violation and represent the most sensitive search performed through the phase space of a multibody decay.
