A measurement of the CP asymmetry difference between Λ c +  → pK−K+ and pπ−π+ decays

Abstract The difference between the CP asymmetries in the decays Λ c +  → pK−K+ and Λ c +  → pπ−π+ is presented. Proton-proton collision data taken at centre-of-mass energies of 7 and 8 TeV collected by the LHCb detector in 2011 and 2012 are used, corresponding to an integrated luminosity of 3 fb−1. The Λ c + candidates are reconstructed as part of the Λ b 0  → Λ c + μ−X decay...
