Description

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.
