  This summary of the working group 2 of DIS 2000 encompasses experimental and
theoretical results of jet physics, open and bound state heavy flavour
production, prompt photon production, next-to-leading order QCD calculations
and beyond, instantons, fragmentation, event shapes, and power corrections,
primarily from deep-inelastic scattering and photoproduction at HERA, but also
from the LEP and Tevatron colliders.
