Measurements of CP violation in the three-body phase space of charmless B± decays

The charmless three-body decay modes B± → K± π+π−, B± → K± K+ K−, B± → π± K+ K− and B± → π± π+ π− are reconstructed using data, corresponding to an integrated luminosity of 3.0  fb−1, collected by the LHCb detector. The inclusive CP asymmetries of these modes are measured to be ACP(B± → K± π+ π−) =...
