【 摘 要 】

In this work a study of the CP asymmetry across the phase space of charmless three-body decays of B±mesons is presented. Four final states containing only charged light mesons are considered: π-π-π+, K-π-π+, K-π-K+and K-K-K+. The observed pattern of the CP asymmetry distribution suggests the action of different mechanisms generating strong phases, which are necessary to give rise to CP violation.
