RT Book, Section T1 Chiral symmetry and mesons in hot and dense matter: recent developments A1 Gómez Nicola, Ángel A1 Fernández Fraile, Daniel AB We review recent results on properties of the meson gas relevant for Heavy Ion Collision and Nuclear Matter experiments, within the framework of chiral lagrangians. In particular, we describe the temperature and density evolution of the sigma and rho poles and its connection with chiral symmetry restoration, as well as the chemical nonequilibrated phase and transport coefficients.
