Abstract
We report on recent calculations in perturbative Quantum Chromodynamics (QCD) and its generalization to Yang-Mills theories with fermions. We summarize the present status of four-loop calculations of the splitting functions for the scale dependence (evolution) of the quark and gluon distributions of hadrons. Five-loop results are presented for the beta function, i.e., the running of the coupling constant, and for hadronic decays of the Higgs boson.
Series This talk is part of the HEP phenomenology joint Cavendish-DAMTP seminar series.
