Search for $CP$ violation in ${\Xi }_c^{+}\to p{K}^{-}{\pi }^{+}$ decays using model-independent techniques

LHCb collaboration, R. Aaij, C. Abellán Beteta +950

A first search for $CP$ violation in the Cabibbo-suppressed ${\Xi }_c^{+}\to p{K}^{-}{\pi }^{+}$ decay is performed using both a binned and an unbinned model-independent technique in the Dal…
