Polarizability of the Nucleon and Compton Scattering
One of the central challenges of hadron physics in the regime of strong (non-perturbative) QCD is to identify the relevant degrees of freedom of the nucleon and to quantitatively explain experimental data in terms of these degrees of freedom. Among the processes studied so far Compton scattering plays a prominent role because of the well understood properties of the electromagnetic interaction....
متن کاملLow Energy Compton Scattering and Nucleon Structure
The low energy virtual Compton scattering process eN → eNγ offers a new and potentially high resolution window on nucleon structure via measurement of so-called generalized polarizabilities (GPs). We present calculations of GPs within heavy baryon chiral perturbation theory and discuss present experimental efforts.
متن کاملDeuteron 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 کاملTheory of deeply virtual Compton scattering on the nucleon
We compute the cross section for leptoproduction of the real photon off the nucleon, which is sensitive to the deeply virtual Compton scattering amplitude with power accuracy. Our considerations go beyond the leading twist and involve the complete analysis in the twist-three approximation. We discuss consequences of the target and lepton beam polarizations for accessing the generalized parton d...
متن کاملNucleon Polarisabilities from Compton Scattering on the Deuteron
An analytic calculation of the differential cross section for elastic Compton scattering on the deuteron at photon energies ω in the range of 25 − 50 MeV is presented to next-to-next-to-leading order, i.e. to an accuracy of ∼ 3%. The calculation is model-independent and performed in the low energy nuclear Effective Field Theory without dynamical pions. The iso-scalar, scalar electric and magnet...
