Comments and Questions

Questions:

• Igal: Are there calculations for a neutron (deuteron) target? Yes, and can share those offline.
• Volker: Is there a functional event generator for these processes? Yes, was written by Derek Glazier and used for several previous studies of both JLab22 and EIC.
• Matt/Patrizia: How well do we understand the non-resonant background, e.g. J/psi+N(pi) production? -> Alessandro/Adam: Phenomenological model from Double Regge approach may provide a reasonable estimate and there are plans to work on this.
• Patrizia: Are there other models on the market beyond VMD? -> Christian: maybe potential from holographic QCD approach?
• Patrizia: How critical is an independent production mechanism compared to e+e-?
