title = "Angular analysis of the low K+K- invariant mass enhancement in B+ →k+K-π+ decays",

abstract = "We study the decay B+→K+K-π+ and investigate the angular distribution of K+K- pairs with invariant mass below 1.1 GeV/c2. This region exhibits both a strong enhancement in signal and very large direct CP violation. We construct a coherent sum model for the angular distribution of the S- and P-wave, and report the ratio of their amplitudes, the relative phase and the forward-backward asymmetry. We also report absolute differential branching fractions and direct CP asymmetry for the decay in bins of MK+K- and the differential branching fractions in bins of MK+π-. The results are based on a data sample that contains 772×106 BB¯ pairs collected at the ϒ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. The result favors the presence of S- and D-waves in low MK+K- region to the detriment of a P-wave.",
