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 ${\mu }_5$, the chemical potential associated to chiral imbalance in a locally $P$-breaking scenario. The a…
