Search for CP violation in Ξ c + → p K - π + decays using model-independent techniques

Abstract

Abstract: A first search for CP violation in the Cabibbo-suppressed Ξc+→pK-π+ decay is performed using both a binned and an unbinned model-independent technique in the Dalitz plot. The studies are based on a sample of proton-proton collision data, corresponding to an integrated luminosity of 3.0fb-1, and collected by the LHCb experiment at centre-of-mass energies of 7 and 8TeV. The data are consistent with the hypothesis of no CP violation.
