TOPICS • Physics Studies with Early Data • Jets, Leptons, Photons, Missing Energy • The Challenge of a light Higgs Boson • Dark Matter measurements and the LHC The LHC is expected to begin operation in 2009. Theorists and experimentalists will be brought together to focus on the early data as well as fundamental issues for the LHC physics program: What can be learned from the early data? The challenges of measuring Missing Energy. The impact of ground, balloon and satellite measurements of Dark Matter on the LHC experiments. The challenge of a light Higgs boson.
