Title: The TREK/E36 experiment at J-PARC

Experiment E36 is planned to run at the J-PARC K1.1BR kaon beamline in 2014-15 using a stopped kaon beam along with the TREK target and detector setup. The decay products of stopped positive kaons will be observed with a large-acceptance toroidal spectrometer capable of tracking charged particles with high resolution, combined with a photon calorimeter with large solid angle and redundant particle identification systems. With the aim to test lepton universality in the K{sub e2}/K{sub μ2} ratio with high precision, the experiment is highly sensitive to new physics beyond the Standard Model. A further goal of E36 is to search for a heavy sterile neutrino in two-body kaon decay, along with additional searches for exotic decay modes including the possibility to produce a dark photon and to observe its decay into an e{sup +}e{sup −} pair. An overview of the planned measurements with E36 will be presented.
