A dispersive estimate of scalar contributions to hadronic light-by-light scattering

We consider the contribution of scalar resonances to hadronic light-by-light scattering in the anomalous magnetic moment of the muon. While the f0(500) has already been addressed in previous work using dispersion relations, heavier scalar resonances have only been estimated in hadronic models so far...
