Advances in perturbative QCD techniques have been crucial for the successful
interpretation of the data collected in Run I of LHC, and for the discovery of
the Higgs boson. I will very briefly highlight some recent additions to the QCD
toolbox, and note how these new tools are likely to be essential for future
precision physics, both in Run II at the LHC, and in view of future hadron and
lepton colliders.Comment: Talk given at the Workshop "LFC15: Physics Prospects for Linear and
Other Future Colliders", ECT*, Trento, 7-11 September 201
