(1+1)-dimensional large-N QCD coupled to adjoint fermions.

We consider 1+1-dimensional QCD coupled to Majorana fermions in the adjoint representation of the gauge group SU(N). Pair creation of partons (fermion quanta) is not suppressed in the large-N limit, where the glueball-like bound states become free. In this limit the spectrum is given by a linear light-cone Schrödinger equation, which we study numerically using the discretized light-cone quantization. We find a discrete spectrum of bound states, with the logarithm of the level density growing approximately linearly with the mass. The wave function of a typical excited state is a complicated mixture of components with different parton numbers. A few low-lying states, however, are surprisingly close to being eigenstates of the parton number, and their masses can be accurately calculated by truncated diagonalizations. 7/93 ⋆ On leave of absence from the Ruder Bošković Institute, Zagreb, Croatia
