Chiral perturbation theory vs. Linear Sigma Model in a chiral imbalance medium
A. A. Andrianov, V. A. Andrianov, D. Espriu
We compare Chiral Perturbation Theory (ChPT) and the Linear Sigma Model (LSM) as realizations of low energy QCD for light mesons in a chirally imbalanced medium. The relations betw…

Chiral perturbation theory in the environment with chiral imbalance
A. A. Andrianov, V. A. Andrianov, D. Espriu
We discuss the description of chiral imbalance imprint in pion matter. It is based on the Chiral Perturbation Theory supplemented by medium induced chiral chemical potential in the…
