Two-photon exchange in dispersion approach
Dmitry Borisyuk, Alexander Kobushkin
We calculate two-photon exchange amplitude for the elastic electron-proton scattering in the framework of dispersion relations. The imaginary part of the amplitude is determined by…
Two-photon exchange at low Q^2
Dmitry Borisyuk, Alexander Kobushkin
We study two-photon exchange for elastic electron-proton scattering at low Q^2. Compact approximate formulae for the amplitudes are obtained. Numerical calculations are done for Q^…
Box diagram in the elastic electron-proton scattering
Dmitry Borisyuk, Alexander Kobushkin
We present an evaluation of box diagram for the elastic scattering with proton in the intermediate state. Using analytic properties of the proton form factors we express the a…
Beam normal spin asymmetry of elastic scattering in the leading logarithm approximation
Dmitry Borisyuk, Alexander Kobushkin
The beam normal spin asymmetry for the elastic scattering is studied in the leading logarithm approximation. We derive the expression for the asymmetry, which is valid for any…
Target Normal Spin Asymmetry of the Elastic ep-Scattering at Resonance Energy
Dmitry Borisyuk, Alexander Kobushkin
We study the target normal spin asymmetry for the reaction at electron energy up to few GeV in the laboratory frame. The asymmetry is proportional to the imaginary part…
