The international High Energy Physics community is in the process of developing a comprehensive and global plan for the coming two decades. Much of this period will be determined by the current Tevatron runs, as well as the operation of the LHC. Both projects are clear priorities for the present and immediate future of the High-Energy frontier and the major effort of the community is concentrated on them. It is clear, however, that now is the time to plan and prepare for the next steps.
The flagship international accelerator project proposed for after the LHC is the development of an e+e- linear collider. In addition, the global plan calls for development of the physics case for a next-generation hadron collider, operating in the ~ 100 TeV energy range (a "VLHC"); a possible luminosity and/or energy upgrade of the LHC; and the identification of R&D requirements in order to develop necessary detector and accelerator technologies. Consideration of all of these items is the purpose of this inaugural workshop, which builds on the effort begun at Snowmass, 2001.
The main objective of the workshop is to begin to
identify and refine the physics case for an upgraded LHC and a (post-LC) next
generation hadron collider (VLHC), to review technologies for machines and detectors,
and to clearly point out areas where R & D will be needed in the future.
Workshop attendance will be limited to 120 attendees. There is no registration
