Factorization and Color-Suppression in Hadronic B->D^(*)npi Decays
Abstract
Description
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 a_1, and a_2/a_1. 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.
Tex, 5 pages, 2 postscript figures plus additional tex macros submitted as a gziped tar file. A postscript version is available from http://www.phys.hawaii.edu/~jorge/postscript/vietnam.ps This replacement version corrects errors in the original preprint and updates the URL link above. The corrections are to the Reported measurement numbers of the polarization in D*+/rho- from B -> D*rho- decays and the BSW parameters. The error in the polarization measurement was not caught in time before publication in the Proceeding of the IInd Recontres du Vietnam (1995). It has been corrected here
