Chiral Perturbation Theory vs. Linear Sigma Model in a Chiral Imbalance Medium

Chiral Perturbation Theory vs. Linear Sigma Model in a Chiral Imbalance Medium

We compare the chiral perturbation theory (ChPT) and the linear sigma model (LSM) as realizations of low energy quantum chromodynamics (QCD) for light mesons in a chirally-imbalanced medium. The relations between the low-energy constants of the chiral Lagrangian and the corresponding constants of th...
