J-PARC Experiment E06 at the Nuclear and Particle Physics Facillity
The TREK Experiment
(Time Reversal Experiment with Kaons)
TREK is an experiment to search for violation of time reversal invariance
in the kaon decay of
planned at the Japan Proton Accelerator Research Complex
The transverse muon polarization (PT)
will be precisely measured with the TREK detector
using the Superconductiong Toroidal Magnet.
This quantity is sensitive also to CP volation origins other than the Standard Model.
An experimental sensitivity of
ΔPT = 10-4
is expected. During the low power period of the accelerator, we plan to perform the
E36 experiment , which
tests the lepton universality in kaon two-body decays and looks for a heavy neutrino.
