Title	μTRISTAN
Abstract	The ultra-cold muon technology developed for the muon g − 2 experiment at J-PARC provides a low-emittance μ^+ beam which can be accelerated and used for realistic collider experiments. We consider the possibility of new collider experiments by accelerating the μ^+ beam up to 1 TeV. Allowing the μ^+ beam to collide with a high-intensity e^− beam at the TRISTAN energy, Ee−=30 GeV, in a storage ring with the same size as TRISTAN (a circumference of 3 km), one can realize a collider experiment with the center-of-mass energy √s=346 GeV, which allows the production of Higgs bosons through vector boson fusion processes. We estimate the deliverable luminosity with existing accelerator technologies to be at the level of 5 × 10^33 cm^−2 s^−1, with which the collider can be a good Higgs boson factory. μ^+μ^+ colliders up to √s=2 TeV are also possible using the same storage ring. They have the capability of producing the superpartner of the muon up to TeV masses.
