Outline of Final Research Achievements

Design optimization was performed for the decay vertex chamber of the charged particle tracking system for the E36 experiment "Search for lepton flavor universality violation in charged kaon decays" at J-PARC. A Spiral Fiber Tracker (SFT), which was a novel technique, was adopted superseding the initial plan of using a Gas Electron Multiplier (GEM) and constructed successfully. Its performance such as the ability of charged particle hit position determination, position resolution and detection efficiency was measured and confirmed to be high enough for an E36 tracking element. Then the total E36 detector was set up including SFT at the J-PARC Hadron Experimental Facility. Using K+ beams measurements were performed and a method was developed and established to extract relevant two-body decay events of Kμ2 and Ke2 for the LFUV analysis. Further, data acquisition was done aiming for required experimental statistical accuracy.
