"In Search of the Quark Anti-Quark Potential"

In this work, we describe the need for a reliable quark anti-quark potential.
We also discuss what the quark gluon plasma is.
We calculate the dissociation of mesons due to absorption of a thermal
gluon in a quark gluon plasma and the dissociation of heavy mesons
due to the effect of color charge screening. The lifetime of
mesons moving with velocity v through a quark gluon plasma at
temperature T is computed. An explicit configuration space potential
is found for the screened interaction between the quarks constituting
the meson. This potential is non-spherical, but axially symmetric about
the direction of v. We solve the Schroedinger equation for the relative
motion of the quarks in this potential, and use the bound-state wave
function as the initial state for the dissociation of the meson.
