Title: Amplitude Analysis of the B+ to phi K*+(892) Decay

Abstract

We perform an amplitude analysis of B{sup {+-}} {yields} {var_phi}(1020)K*(892){sup {+-}} decay with a sample of about 384 million B{bar B} pairs recorded with the BABAR detector. Overall, twelve parameters are measured, including the fractions of longitudinal f{sub L} and parity-odd transverse f{sub {perpendicular}} amplitudes, branching fraction, strong phases, and six parameters sensitive to CP-violation. We use the dependence on the K{pi} invariant mass of the interference between the J{sup P} = 1{sup -} and 0{sup +} K{pi} components to resolve the discrete ambiguity in the determination of the strong and weak phases. Our measurements of f{sub L} = 0.49 {+-} 0.05 {+-} 0.03, f{sub {perpendicular}} = 0.21 {+-} 0.05 {+-} 0.02, and the strong phases point to the presence of a substantial helicity-plus amplitude from a presently unknown source.
