Heavy quark symmetry in isosinglet non-leptonic B-decays

We use a factorization theorem from the soft-collinear effective theory along with heavy quark symmetry to make model independent predictions for (B) over bar (0) --> D-(*)0 M where M = {eta, eta', phi, omega}. Gluon production of these isosinglet mesons is included. We predict the equality of branching fractions in the (B) over bar --> DM and (B) over bar --> D*M channels. with corrections at order Lambda(QCD)/Q and alpha(s)(Q) where Q = m(b), m(c), or E-M. We also predict that Br((B) over bar (0)--> Deta')/Br((B) over bar (0) --> Deta) = tan(2)(theta) = 0.67 and Br((B) over bar --> Dphi)/Br((B) over bar --> Domega) less than or similar to 0.2. where here there are also alpha(s)(rootELambda) corrections. These results agree well with the available data. A test for SU(3) violation in these decays is constructed. (C) 2004 Elsevier B.V. All rights reserved.
