1 A possibility of ring collider for Higgs factory 13 Feb K. Oide (KEK) Inspired by A. Blondel and F. Zimmermann, A High Luminosity e+e- Collider in the LHC tunnel to study the Higgs Boson, V2.1 - V2.7, arxiv: v1 [hep- ex], 24 Dec 2011.
2 Motivations If the Higgs mass is below 130 GeV, an e+e- ring collider may have merits as a Higgs factory: Based on existing technologies which have been proven for 40 years by a number of colliders. The machine will be simple enough, and the operation will be easy and straightforward. The design luminosity will be quickly achieved, for instance after 6 months commissioning. Cheaper construction / operation costs than linear machines. S. Yamashita via A. Blondel and F. Zimmermann
