Observation of the ${\Xi }_c^0\to p{K}^{-}$ decay and measurement of its decay asymmetry

LHCb collaboration, R. Aaij, M. Abdelfatah +1154

A search for the Cabibbo-suppressed decay ${\Xi }_c^0\to p{K}^{-}$ is performed using $pp$ collision data corresponding to an integrated luminosity of $5.4{\mathrm{fb}}^{-1}$, collected by…
