Amplitude analysis of the B±→φK*(892)± decay


Journal Article

We perform an amplitude analysis of B±→φ(1020)K*(892) ± decay with a sample of about 384×106 BB̄ pairs recorded with the BABAR detector. Overall, twelve parameters are measured, including the fractions of longitudinal fL and parity-odd transverse f amplitudes, branching fraction, strong phases, and six parameters sensitive to CP violation. We use the dependence on the Kπ invariant mass of the interference between the JP=1- and 0+ Kπ components to resolve the discrete ambiguity in the determination of the strong and weak phases. Our measurements of fL=0.49±0.05±0. 03, f=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. © 2007 The American Physical Society.
