RT Book, Section T1 Chiral mesons in hot matter A1 Llanes Estrada, Felipe José A1 Peláez Sagredo, José Ramón A1 Gómez Nicola, Ángel AB We review our recent work on thermal meson proper-ties within the Chiral Perturbation Theory framework. We will focus on the pion electromagnetic form factor, stressing its importance for Relativistic Heavy Ion Collisions. We obtain model-independent predictions (based only on chiral symmetry) such as the temperature dependence of the pion electromagnetic charge radius. Imposing unitarity allows to describe the thermal effects of resonances such as the rho meson.
