The Challenges of a Storage Ring-based Higgs Factory

Abstract
The recent discovery-level observation of a Higgs-like particle at the LHC has prompted a number of accelerator physicists at CERN and KEK to investigate whether it is practical or even to possible build a storage ring-based Higgs factory. Already LEP2 operated at a collision energy of ~205 GeV, prompting the question, “Can the Higgs factory be built in the LHC tunnel?” The analysis of this question leads to some surprising and instructive results that show how little freedom that the designers of such a machine may have. This talks starts with the basic physics requirements moves to a succession on difficult performance specifications for the possible collider including one effect that has never been an issue in past storage rings. We also consider whether a 40 km ring, such as Super-Tristan would ease the design challenges.
