摘要
We study the decay B+ -> K+K- =pi(+) and investigate the angular distribution of K+K- pairs with invariant mass below 1.1 GeV/c(2). 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+pi-. The results are based on a data sample that contains 772 x 10(6) B (B) over bar pairs collected at the (sic)(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.
