Outline of Final Research Achievements |
This research program aims for developing algorithms for the "trigger", which selects the collision events of interest by finding a muon, at the LHC, the highest energy accelerator in the world. The research improved the muon trigger algorithm in the ATLAS experiment, one of the international collaboration at the LHC. The study is meant to increase sensitivity for the new physics search at the LHC. This study has achieved to keep the trigger rate (the data transfer rate) low enough while maintaining the efficiency for preserving the events of interest through various improvements on the muon trigger algorithm. We also have developed a new trigger algorithm for the upgraded detector to be installed during the accelerator shutdown 2019-2020. We have proven that the algorithm has achieved expected performance for the new running period.
