CP violation in charmless B± three-body decays: where Flavour Physics meets Hadron Physics

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.
