| Outline of Final Research Achievements |
We performed the search for H->ττ decay mode and finally found the excess over background expectations with an observed significance of 4.5 standard deviations by using LHC/ATLAS Run1 data. It indicates the world first’s evidence for fermion-yukawa coupling and signal strength was consistent with the Standard Model prediction. Moreover based on the success of H->ττ analysis, we extended our activity to the search top quark-Yukawa coupling. By these inclusive searches, The SM Higgs mechanism is considered to be valid in terms of fermion-Yukawa coupling sector within uncertainties. In addition, we built a test bench for Fast tracker R&D in Waseda campus and completed PCB design, prototyping testing, mass production in Japan (yield rate was 100%). 80 boards were transferred to CERN and successfully installed to the ATLAS detector. This achievement would be powerful improvement for data taking at upcoming higher luminosity operation of LHC.
