  We study an extended QCD model in 2D obtained from QCD in 4D by compactifying
two spatial dimensions and projecting onto the zero-mode subspace. This system
is found to induce a dynamical mass for transverse gluons -- adjoint scalars in
QCD(2), and to undergo a chiral symmetry breaking with the full quark
propagators yielding non-tachyonic, dynamical quark masses, even in the chiral
limit. We construct the hadronic color singlet bound-state scattering
amplitudes and study quark-antiquark bound states which can be classified in
this model by their properties under Lorentz transformations inherited from 4D.
