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 (T-violation) in the kaon decay of K⁺→ π⁰μ⁺ν planned at the Japan Proton Aceelerator Research Complex (J-PARC). The transverse muon polarization (P_T) 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 ΔP_T = 10^-4 is expected.
