摘要：
Deep inelastic scattering (DIS) data on F2 structure function accumulated by various collaborations in fixed-target experiments are analyzed in the nonsinglet approximation and within (Formula presented.) 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. © 2022, Pleiades Publishing, Inc.
