Few-quark correlation in hot matters
  We address the issue of three-quark clusters in a medium of finite temperatures and densities. We use the light front approach and utilize a Green function formalism. We consider first the isolated case using a zero-range interaction and introducing an invariant cut-off and then medium effects. The Mott lines are shown for different values of the cut-off.
