Form Factors and Cross Section for J/ψ Dissociation

摘要

We use the QCD sum rules to evaluate the D~*Dπ, DDp and DDJ/ψ form factors as well as the J/ψπ→ open charm cross sections. The form factors are evaluated as a function of the momentum Q~2 of the off-shell meson and the cross sections as a function of s~(1/2).
