초록

We report the measurements of branching fractions and CP violation asymmetries in B-0 -> phi K* decays obtained in an angular analysis using the full data sample of 772 x 10(6) B (B) over bar pairs collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. We perform a partial wave analysis to distinguish among scalar [B-0 -> phi(K pi)(0)*], vector [B-0 -> phi K*(892)(0)] and tensor [B-0 -> phi K-2*(1430)(0)] components, and determine the corresponding branching fractions to be B[B-0 -> phi(K pi)(0)*] = (4.3 +/- 0.4 +/- 0.4) x 10(-6), B[B-0 -> phi K*(892)(0)] = (10.4 +/- 0.5 +/- 0.6) x 10(-6) and B[B-0 -> phi K-2*(1430)(0)] = (5.5(-0.7)(+0.9) +/- 1.0) x 10(-6). We also measure the longitudinal polarization fraction f(L) in B-0 -> phi K*(892)(0) and B-0 -> phi K-2*(1430)(0) decays to be 0.499 +/- 0.030 +/- 0.018 and 0.918(-0.060)(-0.029) +/- 0.012, respectively. The first quoted uncertainties are statistical and the second are systematic. In total, we measure 26 parameters related to branching fractions, polarization and CP violation in the B-0 -> phi K* system. No evidence for CP violation is found.
