Query: Adjoint 2D QCD and Pure 3D QCD: A Comparison of Spectra   We briefly review the 1+1-dimensional SU(N) gauge theory minimally coupled to
an adjoint scalar, based upon a dimensional reduction of 2+1-dimensional pure
gauge theory, which approximates the dynamics of the transversely polarized
gluon. The lightest glueball states are investigated non-perturbatively using
light-front quantisation in the large-N limit a la 't Hooft, and the physical
meaning of the results elucidated. Comparison is made with recent lattice Monte
Carlo data for 3-dimensional quenched QCD.
