Abstract: | The charmless decays B ± → K + K − π ± and B ± → π + π − π ± are reconstructed in a data set of p p 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 A C P ( B ± → K + K − π ± ) = − 0.141 ± 0.040 ( stat ) ± 0.018 ( syst ) ± 0.007 ( J / ψ K ± ) and A C P ( B ± → π + π − π ± ) = 0.117 ± 0.021 ( stat ) ± 0.009 ( syst ) ± 0.007 ( J / ψ K ± ) , where the third uncertainty is due to the C P asymmetry of the B ± → J / ψ K ± reference mode. In addition to the inclusive C P asymmetries, larger asymmetries are observed in localized regions of phase space. |
