Measurements of the branching fractions and helicity amplitudes inBD*decays Academic Article uri icon


  • Using [Formula Presented] of [Formula Presented] data collected at the [Formula Presented] with the CLEO detector using the Cornell Electron Storage Ring, measurements are reported for both the branching fractions and the helicity amplitudes for the decays [Formula Presented] and [Formula Presented] The fraction of longitudinal polarization in [Formula Presented] is found to be consistent with that in [Formula Presented] at [Formula Presented] indicating that the factorization approximation works well. The longitudinal polarization in the [Formula Presented] mode is similar. The measurements also show evidence of nontrivial final-state interaction phases for the helicity amplitudes. 2003 The American Physical Society.
