Low-mass scalar production in $\gamma \gamma$ scattering

High Energy Physics - Phenomenology 2009-11-13 v1

Abstract

We estimate the I=0 scalar meson σ/f0(600)\sigma/f_0(600) γγ\gamma\gamma widths, from ππ\pi\pi and γγ\gamma\gamma scattering data below 700 MeV using an improved analytic K-matrix model.
