摘要：

We consider (1 + 1)-dimensional QCD coupled to scalars in the adjoint representation of the gauge group SU(N). This model results from dimensional reduction of the (2 + 1)-dimensional pure glue theory. In the large-N limit we study the spectrum of glueballs numerically, using the discretized light-cone quantization. We find a discrete spectrum of bound states, with the density of levels growing approximately exponentially with the mass. A few low-lying states are very close to being eigenstates of the parton number, and their masses can be accurately calculated by truncated diagonalizations.
