Chiral Symmetry Restoration at Finite Temperature in the Linear Sigma--Model

D. Metzger, H. Meyer--Ortmanns, H. --J. Pirner

The temperature behaviour of meson condensates $<{\sigma }_0>$ and $<{\sigma }_8>$ is calculated in the $SU(3)\times SU(3)$-linear sigma model. The couplings of the Lagrangian are fitted to the ph…
