Research Title
Lepton Universality and T-violation in Kaon Decay, Solar Axion Search using the CAST detector at CERN


My research interests are currently directed towards a search for non-Standard Model physics ( possible SUSY ) in precision studies of kaon decay at the National Laboratory for High Energy Physics (KEK) in Japan.

This off-site Kaon physics work currently involves two different Kaon decay experiments -- a precise measurement of the branching ratio of
K --> electron + electron_neutrino / K --> muon + muon_neutrino ( E36 ) and a study of CP- or T-Violation in K+ decay ( E06 ) at the new high-intensity hadron facility, J-PARC in Tokai, Japan. The latter is an improved higher sensitivity measurement of T-Violation in Kaon Decay that we performed as KEK (E246).

TREK is an international collaboration involving about 25 physicists from Canada, Japan, Russia, and the USA. For the Canadian contribution to these experiments we have constructed and tested a 256-element scintillating fibre target at TRIUMF.
