Method of Improved Leading Logarithmic Approximation for Study of Polarized Fermions Scattering.
T. Shishkina

The original method of improved leading logarithmic approximation including consideration of collinear photon radiative contribution bremsstrahlung is proposed. Using this method the polarized asymmetries of deep inelastic scattering are calculated and analysed in case of arbitrary polarization states at arbitrary value of momentum transfers. Radiative effects contribution of different nature to the differential cross section of deep inelastic scattering of polarized leptons by polarized nucleons and longitudinal asymmetry as well as transverse one are calculated taking into account the polarization effects. The radiative corrections due to soft and hard photon emission are calculated. The problem of improved leading logarithmic approximation method effectiveness is discussed.
Key words: Improved leading logarithmic approximation method, polarized particles, deep inelastic scattering, asymmetries
