Standard Model & Higgs Working Group
Workshop:
Physics at TeV Colliders
Les Houches 2
May -
20 May 2005
The SM and Higgs WG
will cover calculations
and implementations of cross sections both for QCD, EW as well as Higgs
processes. Indeed, we feel that this aspect of Higgs physics is
best dealt
with by experts in loop/multi-leg calculations with close connection to
Monte-Carlo (MC) techniques and simulations. This session should pay a
particular attention to the very first few year of running of the
LHC making sure that the most important SM processes are well under
control. The impact and the exploitation of the Tevatron experience is
also a central topic.
Meetings and planning of the
WG and subgroups of of the SMH WG, see
