On the bosonic spectrum of QCD(1+1) with SU(N) currents

In this note we calculate the spectrum of two-dimensional QCD. We formulate the theory with SU(N-C) currents rather than with fermionic operators. We construct the Hamiltonian matrix in DLCQ formulation as a function of the h armonic resolution K and the numbers of flavors N-f and colors N-c. The res ulting numerical eigenvalue spectrum is free from trivial multi-particle st ates which obscured previous results. The well-known 't Hooft and large N-f spectra are reproduced. In the case of adjoint fermions we present some ne w results. (C) 2000 Elsevier Science B.V. All rights reserved.
