Description:
Author(s): Antoine Gérardin, Jeremy Green, Oleksii Gryniuk, Georg von Hippel, Harvey B. Meyer, Vladimir Pascalutsa, and Hartmut Wittig The hadronic contribution to the eight forward amplitudes of light-by-light scattering ( γ * γ * → γ * γ * ) is computed in lattice QCD. Via dispersive sum rules, the amplitudes are compared to a model of the γ * γ * → hadrons cross sections in which the fusion process is described by hadronic resonances. Our fram... [Phys. Rev.
