Abstract
The charmless decays B[superscript ±]→K[ superscript ±]π[superscript +]π[superscript -] and B[superscript ±]→K[superscript ±]K[superscript +]K[superscript -] are reconstructed using data, corresponding to an integrated luminosity of 1.0  fb[superscript -1], collected by LHCb in 2011. The inclusive charge asymmetries of these modes are measured as A[subscript CP]( B[superscript ±]→K[ superscript ±]π[superscript +]π[superscript -])=0.032±0.008 (stat)±0.004 (syst)±0.007(J/ψK[superscript ±]) and A[subscript CP](B[superscript ±]→K[superscript ±]K[superscript +]K[superscript -])=-0.043±0.009 (stat)±0.003 (syst)±0.007(J/ψK[superscript ±]), where the third uncertainty is due to the CP asymmetry of the B[superscript ±]→J/ψK[superscript ±] reference mode. The significance of A[subscript CP](B[superscript ±]→K[superscript ±]K[superscript +]K[superscript -]) exceeds three standard deviations and is the first evidence of an inclusive CP asymmetry in charmless three-body B decays. In addition to the inclusive CP asymmetries, larger asymmetries are observed in localized regions of phase space.
