interactions at TRIUMF and off-site K physics experiments at the National
Laboratory for High Energy Physics(KEK) in Japan and the
Brookhaven National Laboratory in New York.
Over the past several years my TRIUMF program has been concentrated on
studies of the semi-leptonic weak interaction. For this purpose, we
constructed a cylindrical pair spectrometer using a large volume drift chamber
and performed several radiative muon capture experiments at TRIUMF. This
program is now finished but we are continuing to use this spectrometer for
studies of the pion form factor and low energy tests of QCD in the rare pion
reactions 
p 
n and 
p 
n.
We are also involved in a new high precision 
-decay experiment which will
accumulate 10
-decay events to search for new physics beyond the highly
successful ``Standard Model". Earlier studies of this decay have been able to
set a limit on the mass of any right-handed vector boson ( M
) to more than
600 GeV, higher than accelerator based experiments can now reach.
My off-site Kaon physics work involves a study of CP-- or T--Violation in rare
K decays. At KEK we are engaged in a measurement of T--Violation in K
decay in E246--a collaboration involving
about 30 physicists from Canada--Japan--Korea--Russia--Taiwan--USA. We
constructed a scintillating fibre target and a cylindrical drift chamber at
TRIUMF and we are now collecting production data. The experiment will be
completed by Fall '98 so we are also getting involved in a new rare decay
experiment K
( BNL 926 ) in New York. This experiment seeks to
detect this very rare process ( a branching ratio of 3 
is
predicted ) in order to determine unequivocably the origin of CP-Violation in
the Standard Model. Prototype construction and Monte Carlo simulations are
currently underway with a goal to having the experiment in operation in
1999-2000.
