Exclusive decays of a heavy pseudoscalar

Bernard Margolis, Howard D. Trottier

Open publisher page 1 citations

Abstract

Branching ratios for two exclusive decay modes of a hidden-heavy-flavor pseudoscalar meson into other heavy mesons are calculated from quantum chromodynamics in lowest-order perturbation theory. Heavy mesons are treated as nonrelativistic quark-antiquark bound states. All parameters are fixed by hadronic and leptonic widths.
