Nucleon polarizabilities and Delta-resonance magnetic moment in chiral EFT
Vladimir Pascalutsa
Recent chiral EFT calculations of nucleon polarizabilities reveal a problem in the current empirical determination of proton's electromagnetic polarizabilities. We also report on t…
Sum rules for light-by-light scattering
Vladimir Pascalutsa, Marc Vanderhaeghen
We derive a set of sum rules for the light-by-light scattering and fusion: , and verify them in lowest order QED calculations. A prominent implication of these sum rules…
Electromagnetic moments of quasi-stable particle
Tim Ledwig, Vladimir Pascalutsa, Marc Vanderhaeghen
We deal with the problem of assigning electromagnetic moments to a quasi-stable particle (i.e., a particle with mass located at particle's decay threshold). In this case, an applic…
A dispersion relation for the pion-mass dependence of hadron properties
Tim Ledwig, Vladimir Pascalutsa, Marc Vanderhaeghen
We present a dispersion relation in the pion-mass squared, which static quantities (nucleon mass, magnetic moment, etc.) obey under the assumption of analyticity in the entire comp…
