Direct calculation of hadronic light-by-light scattering
Jeremy Green, Nils Asmussen, Oleksii Gryniuk +4
We report calculations of hadronic light-by-light scattering amplitudes via lattice QCD evaluation of Euclidean four-point functions of vector currents. These initial results inclu…
Evaluation of the forward Compton scattering off protons: I. Spin-independent amplitude
Oleksii Gryniuk, Franziska Hagelstein, Vladimir Pascalutsa
We evaluate the forward Compton scattering off the proton, based on Kramers-Kronig kind of relations which express the Compton amplitudes in terms of integrals of total photoabsorp…
Lattice QCD calculation of hadronic light-by-light scattering
Jeremy Green, Oleksii Gryniuk, Georg von Hippel +2
We perform a lattice QCD calculation of the hadronic light-by-light scattering amplitude in a broad kinematical range. At forward kinematics, the results are compared to a phenomen…
