Shekhovtsova O. Lepton–hadron interactions with tagged photons

Subject of study: lepton-hadron interaction processes. Objective: theoretical calculations of cross section some processes of the lepton-hadron interaction (electron-positron annihilation, deep inelastic scattering) with tagged photons, estimation of the differential width of five lepton muon decay at the electron spectrum end. Methods: standard diagram technique for momentum space, invariant integration method. Theoretical and practical results, novelty: Taking into account the first order radiative correction, the cross sections for of electron positron annihilation and deep inelastic scattering with photon emission have been calculated. To measure the cross section for electron positron annihilation into pion pair an inclusive approach has been proposed. Field of application: physics of elementary particles
