About
We present the first evidence of CP violation in the B+→ pi+pi-pi+, B+→ K+pi+pi-, B+→ K+K-pi+ and B+→K+K-K+ decays using the 1.0 fb-1 of data collected by the LHCb experiment during 2011. The results show that the 3pi and Kpipi channels present a positive asymmetry while the KKpi and KKK modes present a negative asymmetry. We also study the variation of the CP violation effects in the phase space of each three-body decay. We find significant inhomogeneities that reveal regions with particularly large asymmetries in the pipi and KK low mass regions in B+→pi+pi-pi+ and B+→K+K-pi+ respectively..
