Partial-wave analysis of proton Compton scattering data below the pion-production threshold
Nadiia Krupina, Vadim Lensky, Vladimir Pascalutsa
Low-energy Compton scattering off the proton is used for determination of the proton polarizabilities. However, the present empirical determinations rely heavily on the theoretical…
Sum rules across the unpolarized Compton processes involving generalized polarizabilities and moments of nucleon structure functions
Vadim Lensky, Franziska Hagelstein, Vladimir Pascalutsa +1
We derive two new sum rules for the unpolarized doubly virtual Compton scattering process on a nucleon, which establish novel low- relations involving the nucleon's generalize…
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…
Dissecting the hadronic contributions to by Schwinger's sum rule
Franziska Hagelstein, Vladimir Pascalutsa
The theoretical uncertainty of is currently dominated by hadronic contributions. In order to express those in terms of directly measurable quantities, we consider a sum r…
Spin-dependent sum rules connecting real and virtual Compton scattering verified
Vadim Lensky, Vladimir Pascalutsa, Marc Vanderhaeghen +1
We present a detailed derivation of the two sum rules relating the spin polarizabilities measured in real, virtual, and doubly-virtual Compton scattering. For example, the polariza…
