Radiative electroweak effects in deep inelastic scattering of polarized leptons by polarized nucleons

The one-loop electroweak radiative correction of the lowest order to lepton current for deep inelastic scattering of longitudinally polarized leptons by polarized nucleons is obtained in model independent way. The detailed numerical analysis within kinematical requirements of future polarization collider experiments is performed. The possibility to reduce radiative effects by detection of hard photons is studied.

Radiative Corrections to Moller Scattering of Polarized Particles

Principal contributions to QED radiative effects for Moller scattering of polarized particles are investigated both on the Born level and taking into account radiative corrections (RC). Scattering on the case of longitudinal and transversal polarized targets is also considered. In a general way the expressions for differential cross section and polarization asymmetry (PA) have been defined, and respective graphics for longitudinal and transversal polarization asymmetries and also for radiative corrections to asymmetry are presented. All quantities are presented in terms of covariant variables. The ultrarelativistic approximation was applied for calculations. The results of a computer run are presented.

Electroweak Radiative Effects in Deep Inelastic Interaction of Polarized Leptons and Nucleons

The results for one-loop correction to deep inelastic scattering of longitudinal polarized leptons on longitudinal polarized hadrons are obtained withing the framework of the standard theory of electroweak interactions and ordinary quark-parton model. The on-shell renormalization scheme in t'Hooft-Feynman gauge is applied. The numerical analysis is carried out under conditions of modern particle physics experiments.Particular emphasis is laid on contributions usually ignored at RC procedure --- electroweak corrections to electromagnetic asymmetry and RC to hadronic current. The structure of RC contribution to polarized asymmetries within the framework of QED and electroweak theory is also discused
