Physics Opportunities at Future Hadron Colliders: SuperLHC and VLHC Dr. Ulrich Baur SUNY, Buffalo In order to make progress, High Energy Physics needs to conduct experiments at (much) higher energies than those available now. This talk gives an overview over recent studies of physics opportunites at hadron colliders operating in 100 TeV region and at luminosities about a factor 10 higher than the design luminosity of the CERN Large hadron Collider. Requirements for detector R&D are also briefly discussed.
