Description
We analyze different problems related to the physics of hadrons under extreme conditions of temperature and chemical potentials. On the one hand, we show that the thermal resonances $f_0(500)$ and $K^∗_0(700)$, generated in the framework of Unitarized Chiral Perturbation Theory $\pi\pi$ and $K\pi$ scattering at finite temperature, play an essential role with respect to chiral and $U(1)_A$ restoration. On the other hand, a low-energy effective lagrangian is constructed within ChPT at non-zero chemical potential, considering non-zero isospin and axial chemical potentials.
