STATUS OF PERTURBATIVE QCD EVALUATION OF HADRONIC DECAY RATES OF THE Z AND HIGGS BOSONS
Davison E. Soper, Levan R. Surguladze
Abstract
We review the current status of the high order perturbative QCD evaluation of the hadronic decay rates of the Z and Higgs bosons. A systematic classification of the various types of QCD corrections to O(αs2) and O(αs3) is made and their numerical status is clarified.
