Dalitz Plot Analysis of the Decay B+ -> K+K+K-

Abstract

We perform an analysis of the three-body charmless decay B ± → K ± K ± K ∓ using a sample of 226.0 ± 2.5 million BB pairs collected by the BABAR detector and measure the total branching fraction and CP asymmetry to be B = (35.2 ± 0.9 ± 1.6) × 10 −6 and A CP = (−1.7 ± 2.6 ± 1.5)%. We fit the Dalitz plot distribution using an isobar model and report the measured values of magnitudes and phases of the production coefficients. The decay dynamics is dominated by thefor which we perform a partial-wave analysis in the region m(K + K − ) < 2 GeV/c 2 . We find no evidence of CP violation for individual components of the isobar model. v
