Hadronic light-by-light scattering contribution to the muon g-2 on the lattice
Nils Asmussen, Antoine Gerardin, Jeremy Green +6
We briefly review several activities at Mainz related to hadronic light-by-light scattering (HLbL) using lattice QCD. First we present a position-space approach to the HLbL contrib…
Hadronic light-by-light scattering amplitudes from lattice QCD versus dispersive sum rules
Antoine Gérardin, Jeremy Green, Oleksii Gryniuk +4
The hadronic contribution to the eight forward amplitudes of light-by-light scattering () is computed in lattice QCD. Via dispersive sum rules, the amplitudes are…
Light-by-light forward scattering amplitudes in Lattice QCD
Antoine Gerardin, Jeremy Green, Oleksii Gryniuk +4
We present our preliminary results on the calculation of hadronic light-by-light forward scattering amplitudes using vector four-point correlation functions computed on the lattice…
Evaluation of the forward Compton scattering off protons: II. Spin-dependent amplitude and observables
Oleksii Gryniuk, Franziska Hagelstein, Vladimir Pascalutsa
The forward Compton scattering off the proton is determined by substituting the empirical total photoabsorption cross sections into dispersive sum rules. In addition to the spin-in…
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…
