Аннотация:
Deep inelastic scattering (DIS) data on ${{F}_{2}}$ structure function accumulated by various collaborations in fixed-target experiments are analyzed in the nonsinglet approximation and within $\overline {MS} $ and DIS schemes. The study of high statistics deep inelastic scattering data provided by BCDMS, SLAC and NMC collaborations, is carried out by applying a combined analysis. The application of the deep inelastic scheme leads to the resummation of contributions that are important in the region of large x values. It is found that using the deep inelastic scheme does not significantly change the strong coupling constant itself but does strongly change the values of the twist-4 corrections.
