Probing the parameter space of two-dimensional QCD with eLCQ

Recently, exhaustively-symmetrized discretized light-cone quantization (eLCQ) has been applied to two-dimensional QCD with adjoint fermions (QCD_2A)

in the large N_c limit. The continuous method is complementary to discretized approximations of field theories. It is more suitable to adequately treat singularities

in bound-state equations, but so far limited to low parton numbers. The low-lying bound-state spectra of both massive and massless QCD_2A

have been computed and agree with previous results. This means that discretized approaches are not fundamentally flawed, even when tackling singular kernels. 

We show that eLCQ naturally generalizes to finite N_c, can be used to probe higher excited bound states in the large mass limit, and discuss application to other theories.
