| dc.description | The reaction is investigated in the quark model approach. The quark model predicts that the off-shell contributions from the resonance dominate the production in the threshold region. We find that the coupling constant from the fit to a few total cross section data is small. The results of the total and differential cross sections are presented at different energies, which can be tested in future experiments. If future total cross section data indeed show a resonance structure around 2 GeV as suggested in a recent study, it would be evidence of a non-qqq structure in its wavefunction. |
