(1) Search for muon lepton flavor violation:
We are studying a search for muon lepton flavor violation with un-precedent
precision with high intensity muon sources. The physics motivation on the
search is based on the fact that supersymmetric grand unification models
predict large branching ratios of muon lepton flavor violation. In particular,
the process of muon-electronconversion in a muonic atom is looked for.
(2) Research and Development of High Intense Muon Sources:
We are working to develop a high intense muon source whose muon beamintensity
is 4 orders of magnitude higher than the presently available. It is called
the PRISM project (="Phase Rotated Intense Slow Muon source").
It will be built at the new project of high intense proton machine at Tokai.
(3) Studies of Neutrino Oscillation at Super Kamiokande
We are studying neutrino oscillation at Super Kamiokande which is located
deep underground at Kamioka, Gifu-prefecture. Super Kamiokandeis a water
cherenkov detector to observe neutrinos (a neutralweakly-interacting particle).
The neutrino oscillation is a phenomenathat one type (flavor) of neutrino
changes into a different type ofneutrino. In particular, neutrinos from
the sun, and the neutrinosfrom the earth's atmosphere are studied to observe
(4) Neutrino Factory
We are studying a future possibility to construct a neutrino factory, where
a high intense neutrino beam is available from the decay of muons in the
storage ring. Important physics topics is to determine the mixing matrix
of neutrinos, and to discover CP violation in neutrino oscillation.
(5) Search for Double Beta Decays with Tracking
We are studying a search for double beta decays with beta-ray tracking.
By using a lens system and Image recorders, two beta-rays from double beta
decay events can be recorded with high background suppression. This study
can be done at Toyonaka Campus of Osaka University.
