Abstract

Quantum chromodynamics predictions for the non-singlet structure functions of ep and μp inclusive scattering are tested against experiment. Target mass corrections and leading and next-to-leading terms α c are taken into account. The fits to experimental data are very good; they improve systematically when including second-order corrections. The preferred value for the invariant parameter Λ entering α c is Λ=0.20 ± 0.06 GeV, when second-order and target mass corrections are taken into account.
