Deuteron Compton Scattering and Electromagnetic Polarizabilities of the Nucleon *
Differential cross section of deuteron Compton scattering has been calculated using the Bonn NN-potential, a consistent set of meson-exchange currents and seagulls, and lowest-and higher-order electromagnetic polarizabilities of the nucleon. Estimates of the polarizabilities of the neutron are obtained from recent experimental data. Photon scattering is a powerful tool for probing the structure...
متن کاملCompton Scattering and Generalized Polarizabilities
In recent years, real and virtual Compton scattering off the nucleon have attracted considerable interest from both the experimental and theoretical sides. Real Compton scattering gives access to the so-called electromagnetic polarizabilities containing the structure information beyond the global properties of the nucleon such as its charge, mass, and magnetic moment. These polarizabilities hav...
متن کاملProton spin polarizabilities from polarized Compton scattering
Polarized Compton scattering off the proton is studied within the framework of subtracted dispersion relations for photon energies up to 300 MeV. As a guideline for forthcoming experiments, we focus the attention on the role of the proton’s spin polarizabilities and investigate the most favorable conditions to extract them with a minimum of model dependence. We conclude that a complete separati...
متن کاملVirtual Compton Scattering at Low Energy and the Generalized Polarizabilities of the nucleon
Virtual Compton Scattering on the nucleon: γ * N → γN is a new and rapidly developing field at low and high energies, with the emergence of recent concepts such as Generalized Parton Distributions (GPDs) at high energy, and Generalized Polarizabilities (GPs) at low energy. This lecture is about the low energy part, i.e. for energies in the (γp) center-of-mass mainly up to the ∆(1232) resonance ...
متن کاملSpin polarizabilities and polarizabilities of the nucleon studied by free and quasi-free Compton scattering at MAMI (Mainz)
In addition to the E2/M1 ratio of the N → ∆ transition, the electromagnetic polarizabilities and spin-polarizabilities are important structure constants of the nucleon which serve as sensitive tests of chiral perturbation theory and of models of the nucleon. Recently, these quantities have been investigated experimentally at MAMI (Mainz) by high-precision Compton scattering using hydrogen and d...
