Abstract

The charmless decays B± → K+K-π± and B± → π+π-π± are reconstructed in a data set of pp collisions with an integrated luminosity of 1.0 fb-1 and center-of-mass energy of 7 TeV, collected by LHCb in 2011. the inclusive charge asymmetries of these modes are measured to be ACP(B±→K+K-π±)=-0.141±0.040(stat)±0.018(syst)±0.007(J=ΠK±) and ACP(B± → π+π-π±) = 0.117 ± 0.021 (stat)±0.009 (syst) ± 0.007(J=Π K±), where the theird uncertainty is due to the CP asymmetry of the B± → J=ΠK± reference mode. In addition to the inclusive CP asymmetries, larger asymmetries are observed in localized regions of phase space.
