Mesonic spectra of bosonized QCD2 models Original Research Article

We discuss bosonized two-dimensional QCD with massless fermions in the adjoint and multi-flavor fundamental representations. We evaluate the massive mesonic spectra of several models by using the light-front quantization and diagonalizing the mass operator M2 = 2P+P−. We recover previous results in the case of one-flavor adjoint fermions by using an approximation where pair creation and pair annihilation is suppressed. We find the exact massive spectrum of multi-flavor QCD in the limit of large number of flavors.
