Resumen

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 A CP(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.
