The TREK experiment at the new J-PARC 50 GeV proton accelerator in Japan is searching for new physics beyond the highly successful Standard Model (SM) of particle physics by making a precision measurement of the muon polarization perpendicular to the decay plane in the Kaon decay-- K+ --> mu+ pizero + neutrino. This transverse muon polarization is predicted to be zero in the SM and the final state interaction (FSI) is computed to be very small ( 1:100,000 ) so any non-zero value above this FSI prediction will be a definite indication of new physics.

在日本新的J-PARC 50 GeV质子加速器上进行的TREK实验正在通过精确测量K介子衰变中垂直于衰变平面的μ介子极化- K+ --> μ + pizero +中微子-来寻找非常成功的粒子物理学标准模型之外的新物理学。这种横向μ子极化在SM中被预测为零，并且最终状态相互作用（FSI）被计算为非常小（1：100，000），因此任何高于此FSI预测的非零值都将是新物理的明确指示。
