Query: Hadronic Molecules and Scattering Amplitudes from the Nonrelativistic
  Quark Model   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 K$\pi$, 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 K$\bar{\rm K}\pi\pi$ and $\phi\pi^0\gamma$ decay modes of the
$\theta(1710)$.
