Impact of double-logarithmic electroweak radiative corrections on the non-singlet structure functions at small x

Abstract

In the QCD context, the non-singlet structure functions of u and d -quarks are identical, save the initial quark densities. Electro-weak radiative corrections, being flavor-dependent, bring further difference between the non-singlets. This difference is calculated in the double-logarithmic approximation and estimated numerically.PACS numbers:
