Abstract

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 A_CP(B^±→K^±π⁺π^-)=+0.025±0.004±0.004±0.007, A_CP(B^±→K^±K⁺K^-)=-0.036±0.004±0.002±0.007, A_CP(B^±→π^±π⁺π^-)=+0.058±0.008±0.009±0.007, A_CP(B^±→π^±K⁺K^-)=-0.123±0.017±0.012±0.007, where the first uncertainty is statistical, the second systematic, and the third is due to the CP asymmetry of the B^±→J/ψK^± reference mode. The distributions of these asymmetries are also studied as functions of position in the Dalitz plot and suggest contributions from rescattering and resonance interference processes.
