Large-n pion scattering, finite-temperature effects and the relationship of the f(0)(500) with chiral symmetry restoration

In this work, we review how the mass and the width of the f(0)(500) pole behave in a regime where temperature is below the critical chiral transition value. This is attained by considering a large-N O(N +1)/O(N) invariant Nonlinear Sigma Model (NLSM) such that we can study the dynamical generation o...
