Description
We study QCD in 1+1 dimensions focusing on meson formation in the vacuum. Utilizing a mass-like Callan-Symanzik regulator, we investigate the flow of the four-quark vertex in a Fierz complete basis. The couplings diverge in the point-like limit, signaling bound state formation. We progress with resolving some momentum dependencies by invoking a Hubbard-Stratonovich transformation. For heavy quarks, the non-relativistic limit enables us to include the full momentum dependence and all emergent mesonic degrees of freedom. Highlighting the relation to the quantum mechanical two-body problem, we provide explicit expressions for their propagator, space-dependent fields and Yukawa (quark-meson) couplings.
