摘要：

The influence of lowest-order QCD corrections on the Drell-Yan cross section Q4( dσ dQ2)(τ, Q2) is determined and compared with the asymptotic freedom (AF) corrections. The perturbative calculation exhibits the AF-characteristics of a (strongly) rising Q2-dependence for √τ≲0.1 (qg-scattering) and falling for √τ≳0.2 (qq̄-annihilation). Qualitative agreement between the two calculation methods in the entire √τ-range is obtained with αs = 0.3. © 1979.
