  The search for new phenomena at hadron colliders requires a good
understanding of QCD processes. The analysis of multi-jet signatures in the top
quark search at the Tevatron is one example, forward jet-tagging and rapidity
gap techniques in the analysis of weak boson scattering events at the LHC will
be another important application. These topics are discussed in the context of
multi-parton/multi-jet QCD processes. Also described are some of the
calculational tools, like amplitude techniques and automatic code generation
for tree level processes.
