Chiral extrapolation of the sigma and rho mesons from dispersion relations and Chiral Perturbation Theory

G. Ríos, A. Gómez Nicola, C. Hanhart +1

We review our recent study of the pion mass dependence of the rho and sigma resonances, generated from one-loop SU(2) Chiral Perturbation Theory (ChPT) with the Inverse Amplitude M…
