Query: Strong Coupling Model for String Breaking on the Lattice (LATTICE'98)   A model for string breaking on the lattice is formulated using strong
coupling ideas. It gives an explicit picture of string breaking, in the
presence of dynamical quarks, as a mixing process between a string state and a
two-meson state. An analysis of the Wilson loop shows that the evolution of the
mixing angle as a function of separation may obscure the expected crossover
effect. If a sufficiently extensive mixing region exists then an appropriate
combination of transition amplitudes may help reveal the effect. The
sensitivity of the mixing region to the values of the meson energy and the
dynamical quark mass is explored.
