Low-energy limit of the $O(4)$ quark-meson model from the functional renormalization group approach

Jürgen Eser, Florian Divotgey, Mario Mitter +1

We compute the low-energy limit of the $O(4)$-symmetric quark-meson model as an effective field theory for Quantum Chromodynamics within the Functional Renormalization Group (FRG)…
