Abstract
A search for and violation in charmless four-body decays is performed using triple-product asymmetry observables. It is based on proton-proton collision data collected by the LHCb experiment at center-of-mass energies of 7, 8 and 13 TeV, corresponding to a total integrated luminosity of . The - and -violating asymmetries are measured both in the integrated phase space and in specific regions. No evidence is seen for violation. -parity violation is observed at a significance of 5.8 standard deviations.
