$\mu$TRISTAN

Abstract

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, $E_{e^{-}}=30$ GeV, in the storage ring with the same size as TRISTAN (the circumference of 3 km), one can realize a collider experiment with the center-of-mass energy $\sqrt{s}=346$ GeV, which allows productions of the Higgs bosons through the vector boson fusion processes. We estimate the deliverable luminosity with existing accelerator technologies to be at the level of $5\times 10^{33}$ cm${}^{-2}$ s${}^{-1}$, with which the collider can be a good Higgs boson factory. The ${\mu }^{+}{\mu }^{+}$ colliders up to $\sqrt{s}=2$ TeV are also possible by using the same storage ring. They have a capability of producing the superpartner of the muon up to TeV masses.
