Abstract:
While we all hope that LHC will be a `New Physics machine', we know with
certainty that it will be a `QCD machine': the overwhelming majority of
LHC events will be QCD-dominated. In order to understand possible new
physics scenarios, we will need to master QCD effects with an unprecedented
degree of precision. This challenge, together with some
new theoretical insight, sometimes coming from unexpected directions,
has generated massive progress in our understanding of perturbative QCD,
and in the efficiency of the calculational tools that will be needed at LHC.
I will review some of this recent progress, touching upon the
physics of QCD jets, the determination of parton distributions, new
techniques for NLO calculations, and new results concerning the structure
of infrared and collinear singularities to all orders in perturbation
theory.
