Abstract
We use dimensional reduction techniques to relate real time finite T c orrelation functions in (2 + 1)-dimensional QCD to bound state paramet ers in a generalized 't Hooft model with an infinite number of heavy q uark and adjoint scalar fields. While static susceptibilities and corr elation functions of the DeTar type can be calculated using only the l ight (static) gluonic modes, the dynamical correlators require the inc lusion of the heavy modes. In particular we demonstrate that the leadi ng T perturbative result can be understood in terms of the bound state s of the 2D model and that consistency requires bound state trajectori es composed of both quarks and adjoint scalars.
