Structure and Dynamics of Charmonium
Kevin L. Haglin
Abstract
We apply a confining qq potential to charmonium and open charm in order to model wave functions and to begin studying structure. Results (in momentum space) provide form-factor input to a four-flavor effective chiral Lagrangian which models dynamics of charmonium in hot hadronic matter. Estimates are made for J/ψdissociation cross sections and rates within a fireball. Our study attempts to improve on previous comover suppression models since it includes gauge-invariant form-factor formalism constrained by quark-model phenomenology.
