A search for CP violation in Λb 0→pK− and Λb 0→pπ− decays is presented using a sample of pp collisions collected with the LHCb detector and corresponding to an integrated luminosity of 3.0fb−1. The CP -violating asymmetries are measured to be ACP pK−=−0.020±0.013±0.019 and ACP pπ−=−0.035±0.017±0.020, and their difference ACP pK−−ACP pπ−=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.
