Радиационные эффекты в процессах электрослабого взаимодействия поляризованных лептонов и поляризованных нуклонов в рамках неминимальных калибровочных моделей

Abstract

All types of electroweak asymmetries in deep inelastic scattering of polarized leptons on polarized nucleons are considered in the quark-parton model and within the framework of nonminimal gauge interactions. It is discovered that the difference in the results increases with the energy of incident leptons and reaches its maximum for largest possible values of scaling variable y. The covariant formulas for radiative corrections to asymmetries are derived in improved leading logarithm approximation. Accuracy of using method is obtained. It is shown to be necessary to take into account radiative effects for precision analysis of electroweak asymmetry measurements.
