Thermal hadron resonances and Ward identities: results for the QCD phase diagram
Angel Gómez Nicola, Jacobo Ruiz de Elvira, Andrea Vioque-Rodríguez
We review recent work regarding the role of light scalar resonances at finite temperature for chiral symmetry and restoration. The results obtained are based on unitarized…

Pion scattering, light resonances and chiral symmetry restoration at nonzero chiral imbalance and temperature
Angel Gómez Nicola, Patricia Roa-Bravo, Andrea Vioque-Rodríguez
We calculate the pion scattering amplitude at nonzero temperature and nonzero , the chemical potential associated to chiral imbalance in a locally -breaking scenario. The a…
