Contribution

It provides new exact solutions for the mesonic spectra of multi-flavor QCD in the large flavor limit, extending previous single-flavor results.

Findings

Recovered known spectra for one-flavor adjoint fermions

Derived exact spectra for multi-flavor QCD at large flavors

Demonstrated the effectiveness of light-front quantization in spectrum calculation

Abstract

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 $M^2=2P^+P^- $. We recover previous results in the case of one flavor adjoint fermions and we find the exact massive spectrum of multi flavor QCD in the limit of large number of flavors.
