Relating the pion decay constant to the chiral restoration temperature
N. Bilić, J. Cleymans, M. D. Scadron
Abstract
We review the relationship between the pion decay constant fπ, the chiral symmetry restoration temperature Tc and the phenomenology of low energy chiral symmetry breaking in view of the recent confirmation of the existence of a sigma meson with a mass of 600-700 MeV.
