S-wave pion-pion scattering lengths from nucleon-meson fluctuations
Jürgen Eser, Jean-Paul Blaizot
We present calculations of the -wave isospin-zero and isospin-two pion-pion scattering lengths within a nucleon-meson model with parity doubling. Both scattering lengths are com…
Fluctuation-induced higher-derivative couplings and infrared dynamics of the Quark-Meson-Diquark Model
Niklas Cichutek, Florian Divotgey, Jürgen Eser
In a qualitative study, the low-energy properties of the -symmetric Quark-Meson-Diquark Model as an effective model for two-color Quantum Chromodynamics…
Low-energy limit of the O(4) quark-meson model
Jürgen Eser, Florian Divotgey, Mario Mitter
We study the generation of low-energy couplings induced by quantum fluctuations within the O(4)-symmetric quark-meson model. To this end, we compute the functional renormalization…
Dynamical generation of low-energy couplings from quark-meson fluctuations
Florian Divotgey, Jürgen Eser, Mario Mitter
We extend our recent computation of the low-energy limit of the linear O(4) Quark-Meson Model. The present analysis focuses on the transformation of the resulting effective action…
Low-energy limit of the quark-meson model from the functional renormalization group approach
Jürgen Eser, Florian Divotgey, Mario Mitter +1
We compute the low-energy limit of the -symmetric quark-meson model as an effective field theory for Quantum Chromodynamics within the Functional Renormalization Group (FRG)…
