Description
Two-dimensional QCD was first studied by G. 't Hooft as a model for mesons in the limit of an infinite number of colours where it admits an exact solution. We investigate the model with the FRG at finite number of colours in the vacuum and present the first stages of our study towards dynamical hadronization in this model. In particular, we derive how local four-fermion interactions emerge from the quark-gluon dynamics and study their flow under the FRG in a Fierz-complete ansatz. Emphasizing the importance of Fierz-completeness and the two-dimensional features, we show that the flow equations signal the formation of mesonic bound states.
