Collider Physics

We have good reason to believe that a breakthrough in our understanding of particle physics, especially in the nature of electroweak symmetry breaking, is within reach of the current collider physics program. The upgraded Tevatron experiments will collect a data sample over the period 2002-2005 that is a factor of 20 larger than the previous sample, with the potential of collecting a sample up to 150 times larger before 2008. The LHC will turn on in 2007-2008 with an energy 7 times that of the Tevatron. As a result of this program, one hopes to gain dramatic new insights into the nature of the weak forces and perhaps its relation to gravity.

However, in order to recognize and analyze new physics processes, a detailed understanding of Standard Model physics is required. From this perspective, the problems faced by high-energy physics experiments at hadron colliders are complex and require a wide range of expertise. Recently, there has been remarkable progress in theoretical calculations directly relevant for new discoveries at the forthcoming collider experiments. However, in order to realize this potential, a very close collaboration of physicists working in different subfields of high-energy physics -- experiment, QCD theory, electroweak theory and physics beyond the SM -- will be required. The purpose of this workshop is to stimulate such collaboration.

We anticipate that such topics as perturbative calculations, Monte Carlo event generators, status and logic of various resummation techniques at hadron colliders, structure functions and jet algorithms will be discussed in detail in the QCD part. $W$ and $Z$ production, CP-violation, top-production and Higgs production will be discussed in the Electroweak part, while supersymmetry phenomenology and low scale gravity effects will be discussed in the New Physics part. We also plan to include a component on lattice gauge theory and its connection to the recent advances in continuum perturbation theory.
