Delta electromagnetic form factors and quark transverse charge densities from lattice QCD
C. Alexandrou, T. Korzec, G. Koutsou +5
We discuss the techniques to extract the electromagnetic Delta form factors in Lattice QCD. We evaluate these form factors using dynamical fermions with smallest pion mass of about…
Chiral effective-field theory with a resonance and heavy fields
Vladimir Pascalutsa
Several conceptual points concerning the inclusion of the (1232) resonance in the framework of chiral effective-field theory are discussed, with an emphasis on the problem of po…
Predictive powers of chiral perturbation theory in Compton scattering off protons
V. Lensky, V. Pascalutsa
We study low-energy nucleon Compton scattering in the framework of baryon chiral perturbation theory (BPT) with pion, nucleon, and (1232) degrees of freedom, up to and includ…
Predictions of chiral perturbation theory for Compton scattering off protons
V. Lensky, V. Pascalutsa
We compute the Compton scattering off the nucleons in the framework of manifestly covariant baryon chiral perturbation theory (BPT). The results for observables differ substanti…
Quark transverse charge densities in the from lattice QCD
Constantia Alexandrou, Tomasz Korzec, Giannis Koutsou +5
We extend the formalism relating electromagnetic form factors to transverse quark charge densities in the light-front frame to the case of a spin-3/2 baryon and calculate these tra…
