Konchatnij M. The radiative corrections to processes of electron-hadron interactions taking into account of the particle polarization

The thesis is devoted to the study of the polarized electron-hadron interaction processes. The second-order radiative correction to the electron current tensor, caused by the double hard photon emission and additional e+e- pair production as well by the loop-corrected single photon emission, has been obtained for the case of longitudinally polarized electron. The Born cross-section for the polarized deep-inelastic scattering with a tagged photon of the longitudinally polarized electron off the polarized proton target and the model-independent radiative correction to it have been computed. The analytical expressions for di-pion invariant mass distribution in the initial-state-radiative process e+e- annihilation in the two charged pions and foton the have been derived. The dependence of the total radiative correction on the di-pion invariant mass and other parameters, which define the selection rules, has been investigated.
