Measurements of $CP$ asymmetries in charmless four-body ${\Lambda }_b$ and ${\Xi }_b^0$ decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +841

A search for $CP$ violation in charmless four-body decays of ${\Lambda }_b$ and ${\Xi }_b^0$ baryons with a proton and three charged mesons in the final state is performed. To cancel out product…
