Calculating Charmonium Dissociation in a Coulomb Gauge QCD Quark Model

We describe the derivation of an effective Hamiltonian which involves explicit hadron degrees of freedom and consistently combines chiral symmetry and color confinement. We use a field theoretical method known as Fock‐Tani (FT) representation and a microscopic relativistic quark model formulated in the context of Coulomb gauge QCD. Using this relativistic hadron Hamiltonian, we evaluate the dissociation cross section of J/ψ‐ρ into D‐mesons.
