| Abstract: | All QCD corrections in hadron-initiated lepton-pair production are questionable for Q2?100 GeV2 since a perturbative expansion is not justified in this kinematical range. Application of the renormalization group (RG) program at Z0 energies is meaningful. We exhibit the size of the non-log correction terms, introduce experimental tests, and point to the assumptiona inherent in Drell-Yan (DY) type analyses. |
