Scalar meson contributions to aμ from hadronic light-by-light scattering
Using an effective σ/f0(500) resonance, which describes the ππ→ππ and γγ→ππ scattering data, we evaluate its contribution and the ones of the other scalar mesons to the hadronic light-by-light (HLbL) scattering component of the anomalous magnetic moment aμ of the muon. We obtain the conservative ran...
