Factorization and Color-Suppression in Hadronic B->D(*)npi Decays
Abstract
The factorization hypothesis and color-suppression are investigated by analyzing the largest, to date, sample of B mesons. In all, 20 hadronic two-body decay modes are reconstructed using 2.04 fb-1 of data collected with the CLEOII detector. We measure the branching fraction of five class I and five class III decay modes and set upper limits on branching fractions of ten class II decays. The branching fraction measurements are used to determine the BSW parameters a1, and a2/a1. In addition, we measure the fraction of B-> D*+ rho- decays which decay longitudinally polarized. The results are found to be consistent with factorization and color-suppression.
