Search for $CP$ violation using $\hat{T}$-odd correlations in $B^0\to p\bar{p}{K}^{+}{\pi }^{-}$ decays

Abstract

A search for $CP$ and $P$ violation in charmless four-body $B^0\to p\bar{p}{K}^{+}{\pi }^{-}$ decays is performed using triple-product asymmetry observables. It is based on proton-proton collision data collected by the LHCb experiment at centre-of-mass energies of $7$, $8$ and $13$ TeV, corresponding to a total integrated luminosity of $8.4$ fb${}^{-1}$. The $CP$- and $P$-violating asymmetries are measured both in the integrated phase space and in specific regions. No evidence is seen for $CP$ violation. $P$-parity violation is observed at a significance of 5.8 standard deviations
