Nonleptonic decays to , and other final states in Factorization
We consider nonleptonic Cabibbo--allowed decays in the
factorization approximation. We calculate nonleptonic decays of the type and relative to
and where we include among the
pseudoscalar states(P) and the vector states(V) the newly discovered
resonances, and . In the ratio of decays to
and relative to the decays to these states,
the poorly known decay constants of and cancel leading
to predictions that can shed light on the nature of these new states. In
general, we predict the decays to be larger than the corresponding
decays and in particular we find the branching ratio for can be between four to five times the branching ratio
for . This enhancement of branching
ratios follows primarily from the fact that more partial waves contribute in
decays than in decays. Our predictions are largely
independent of model calculations of hadronic inputs like form factors and
decay constants.Comment: 16 pages LaTe
