Abstract

A search for 𝐶⁢𝑃 and 𝑃 violation in charmless four-body 𝐵0→𝑝⁢¯𝑝⁢𝐾+⁢𝜋− 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 8.4 fb−1. The 𝐶⁢𝑃- and 𝑃-violating asymmetries are measured both in the integrated phase space and in specific regions. No evidence is seen for 𝐶⁢𝑃 violation. 𝑃-parity violation is observed at a significance of 5.8 standard deviations.
