| Outline of Final Research Achievements |
The LHC restarted operation in 2015 at a new centre-of-mass energy of 13 TeV. A target of this research is to discover long-lived gluinos with the ATLAS detector, which are predicted from the Supersymmetric Standard Model incorporating the Higgs boson with a mass of 125 GeV. The SemiConductor Tracker plays an essential role for this search, then we achieved to exploit the potential in 2015 as well as 2016. We also developped dedicated algorithms for long-lived gluinos. As a result, no events are observed in the signal region, and a gluino mass below approximately 2000 GeV is excluded at 95% confidence level for a lifetime from 0.01 ns to 10 ns.
