Title	Hadronic molecules and scattering amplitudes from the nonrelativistic quark model
Contributors	T Barnes (SERC Rutherford Appleton Lab.)
Abstract	This report summarizes recent calculations of low-energy hadron-hadron scattering amplitudes in the nonrelativistic quark potential model, which assume that the scattering mechanism is a single interaction (usually OGE) followed by constituent interchange. We refer to the scattering diagrams as "quark Born diagrams". For the cases chosen to isolate this mechanism, I=2 pi pi, I=3/2 Kpi, KN and NN, the results are usually in good agreement with experimental S-wave scattering amplitudes given standard potential-model parameters. These calculations also lead to predictions of vector-vector bound states, one of which may be the theta(1710). This assignment can be tested by searches for KK pi pi and phi pi0 gamma decay modes ofthe theta(1710).
