Experimental evidences of CP violation in charged charmless three-body B decays

We present CP violation investigations on B±→h±h+h−(h=p,Kπ) decays in the LHCb experiment. The inclusive charge asymmetries of these modes are measured. In addition, we observe large local asymmetries in several regions of the phase space. This is the first evidence for CP violation in decays involving baryons in the channel .
