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 1TeV. 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 × 1033 cm-2 s-1, with which the collider can be a good Higgs boson factory. μ + μ + colliders up to s = 2TeV are also possible using the same storage ring. They have the capability of producing the superpartner of the muon up to TeV masses.
