A comment on hadronic charm decays

Abstract

We give arguments in favor of the compatibility with standard physics of some large nonleptonic branching fractions in Cabibbo--forbidden $D^{+}$ decays, contrary to a recent claim in the literature.

Comments: 8 pages, 4 tables. A few changes in the text, following revised version of ref. 6. New reference added, no change in the numerical results
