A note on scalar meson dominance

High Energy Physics - Phenomenology 2019-10-30 v2 Nuclear Theory

Abstract

We consider chiral perturbation theory with an explicit broad σ\sigma-meson and study its contribution to the scalar form factors of the pion and the nucleon. Our goal is to learn more about resonance saturation in the scalar sector.
