A search for CP violation in Λ0b→pK− and Λ0b→pπ− decays is presented using a sample of pp collisions collected with the LHCb detector and corresponding to an integrated luminosity of 3.0 fb−1. The CP-violating asymmetries are measured to be ApK−CP=−0.020±0.013±0.019 and Apπ−CP=−0.035±0.017±0.020, and their difference ApK−CP−Apπ−CP=0.014±0.022±0.010, where the first uncertainties are statistical and the second systematic. These are the most precise measurements of such asymmetries to date.

Abstract
A search for CP violation in Λ0b→pK− and Λ0b→pπ− decays is presented using a sample of pp collisions collected with the LHCb detector and corresponding to an integrated luminosity of 3.0 fb−1. The CP-violating asymmetries are measured to be ApK−CP=−0.020±0.013±0.019 and Apπ−CP=−0.035±0.017±0.020, and their difference ApK−CP−Apπ−CP=0.014±0.022±0.010, where the first uncertainties are statistical and the second systematic. These are the most precise measurements of such asymmetries to date.File in questo prodotto:
