Search for CP violation in Xi(+)(c) -> pK(-) pi(+) decays using model-independent techniques

A first search for CP violation in the Cabibbo-suppressed Ξ+c→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 coll...

Descrição
Resumo:A first search for CP violation in the Cabibbo-suppressed Ξ+c→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.
