description | <!--HTML-->We present the first evidence of CP violation in the B<sup>+</sup>→ pi<sup>+</sup>pi<sup>-</sup>pi<sup>+</sup>, B<sup>+</sup>→ K<sup>+</sup>pi<sup>+</sup>pi<sup>-</sup>, B<sup>+</sup>→ K<sup>+</sup>K<sup>-</sup>pi<sup>+</sup> and B<sup>+</sup>→K<sup>+</sup>K<sup>-</sup>K<sup>+</sup> decays using the 1.0 fb<sup>-1</sup> 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<sup>+</sup>→pi<sup>+</sup>pi<sup>-</sup>pi<sup>+</sup> and B<sup>+</sup>→K<sup>+</sup>K<sup>-</sup>pi<sup>+</sup> respectively. |
