Compton scattering from protons and neutrons provides important insight into the structure
of the nucleon. For photon energies up to about 300 MeV, the process can be parameterised …

We review the current state of knowledge of the nucleon polarizabilities and of their role in
nucleon Compton scattering and in hydrogen spectrum. We discuss the basic concepts, the …

We study low-energy nucleon Compton scattering in the framework of baryon chiral
perturbation theory (B χ PT) with pion, nucleon, and Δ (1232) degrees of freedom, up to and …

We analyse the proton Compton-scattering differential cross section for photon energies up
to 325 MeV using Chiral Effective Field Theory (χEFT) and extract new values for the electric …

The proton polarizability effect in the muonic-hydrogen Lamb shift comes out as a prediction
of baryon chiral perturbation theory at leading order and our calculation yields Δ E^(pol)(2P …

Electromagnetic form factors of the nucleon in the spacelike region are investigated within
the framework of a covariant and confining Nambu–Jona-Lasinio model. The bound-state …

We update the predictions of the SU (2) baryon chiral perturbation theory for the dipole
polarisabilities of the proton,{α _ E1,\, β _ M1\} _p={11.2 (0.7),\, 3.9 (0.7)\} * 10^-4 α E 1, β M …

We present a relativistic formulation of pion loop corrections to the coupling of photons with
nucleons on the light front. Vertex and wave function renormalization constants are …

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 …

We report observables for elastic Compton scattering from 3 He in Chiral Effective Field
Theory with an explicit Δ(1232) Δ (1232) degree of freedom (χ χ EFT) for energies between …
