Abstract

En 中文

The ultra-cold muon technology developed for the muon g - 2 experiment at J-PARC provides a low-emittance mu(+) beam which can be accelerated and used for realistic collider experiments. We consider the possibility of new collider experiments by accelerating the mu(+) beam up to 1 TeV. Allowing the mu(+) 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 root 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 x 10(33) cm(-2) s(-1), with which the collider can be a good Higgs boson factory. mu(+)mu(+) colliders up to root 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.
