Выдержка

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 the linear sigma model are established as well as the expressions for the
decay constant of p-meson in the medium and for the mass of the a0. In the large Nc count taken
from QCD the correspondence of ChPT and LSM is remarkably good and provides a solid ground for
the search of chiral imbalance manifestations in pion physics. A possible experimental detection of
chiral imbalance (and therefore a phase with local parity breaking) is outlined in the charged pion
decays inside the fireball.
