Semiclassical Quark Model Of the Nuclear Matter Response

The longitudinal response function $R(q,w)$\ of nuclear matter is calculated in a semiclassical quark model. The model has a many- body string-flip potential that confines quarks into hadrons and avoids color van der Waals forces. Molecular dynamics simulations are used to calculate $R(q,w)$\ in one space dimension for a variety of momentum transfers $q$\ and excitation energies $w$. The response function decreases with density (compared to a free hadron response) because of quark exchange between hadrons.
