Theoretical Developments on Hard QCD Processes at Colliders

Abstract

I review recent theoretical progress on the description of heavy quark, jet and gauge boson production at colliders within perturbative QCD. Particular emphasis is put on the improved understanding of fragmentation phenomena, resummation of large logarithmic corrections and on precision calculations beyond the next-to-leading order.
