A Note on the J/psi Strong Couplings
A. Deandrea🇫🇷 · G. Nardulli🇮🇹 · A.D. Polosa🇨🇭
Abstract
In this note we present an evaluation of the couplings JD(*)D(*) and JD(*)D(*)pi in the Constituent Quark Model. These couplings are a crucial ingredient in the calculation of cross sections for the processes pi J/psi -> D(*)Dbar(*), an important background for the J/psi suppression signal in quark-gluon plasma.
