The fractions of longitudinal polarization f L of the vector-tensor and vector-vector decay modes are measured to be 0.853 + 0.061 − 0.069 ± 0.036 and 0.506 ± 0.040 ± 0.015 , respectively. Overall, twelve parameters are measured for the vector-vector decay and seven parameters for the vector-tensor decay, including the branching fractions and parameters sensitive to C P violation.7 p.application/pdfeng(c) American Physical Society, 2007Física de partículesExperimentsParticle physicsExperimentsinfo:eu-repo/semantics/article5516862019-09-17info:eu-repo/semantics/openAccess
