Abstract
With a sample of about 227x10{sup 6} BB-bar pairs recorded with the BABAR detector we perform a full angular analysis of the decay B{sup 0}{yields}{phi}K{sup *0}(892). We make novel measurements of five parameters sensitive to CP violation. We also measure the branching fraction to be (9.2{+-}0.9{+-}0.5)x10{sup -6} and determine the fractions of longitudinal and parity-odd transverse contributions as f{sub L}=0.52{+-}0.05{+-}0.02 and f{sub perpendicular}=0.22{+-}0.05{+-}0.02. The phases of the parity-even and parity-odd transverse amplitudes relative to the longitudinal amplitude are found to be {phi}{sub parallel}=2.34{sub -0.20}{sup +0.23}{+-}0.05 rad and {phi}{sub perpendicular}=2.47{+-}0.25{+-}0.05 rad. We also observe the decay B{sup 0}{yields}{phi}K*{sup 0}(1430)
