Temperature Dependence of Hadron Masses from the Zimanyi-Moszkowski   Model
  An extended version of the Zimanyi-Moskowski (ZM) model has been used to calculate the temperature dependence of the hadronic masses. The calculation of meson masses in the Random Phase Approximation (RPA) gives an increase in the $\sigma$, $\omega$ and $\pi$ effective masses with temperature.
