Title: Angular analysis of B 0 φ K * decays and search for C P violation at Belle

Abstract

Here, we report the measurements of branching fractions and C P violation asymmetries in B 0 φ K * decays obtained in an angular analysis using the full data sample of 772 × 10 6 B B ¯ pairs collected at the Υ ( 4 S ) resonance with the Belle detector at the KEKB asymmetric-energy e + e - collider. Furthermore, we perform a partial wave analysis to distinguish among scalar [ B 0 φ ( K π ) 0 * ], vector [ B 0 φ K * ( 892 ) 0 ] and tensor [ B 0 φ K 2 * ( 1430 ) 0 ] components, and determine the corresponding branching fractions to be B [ B 0 φ ( K π ) 0 * ] = ( 4.3 ± 0.4 ± 0.4 ) × 10 - 6 , B [ B 0 φ K * ( 892 ) 0 ] = ( 10.4 ± 0.5 ± 0.6 ) × 10 - 6 and B [ B 0 φ K 2 * ( 1430 ) 0 ] = ( 5.5 - 0.7 + 0.9 ± 1.0 ) × 10 - 6 . We also measure the longitudinal polarization fraction f L in B 0 φ K * ( 892 ) 0 and B 0 φ 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 C P violation in the B 0 φ K * system. No evidence for C P violation is found.
