The lab searches for evidence of entirely new laws of nature in the ATLAS experiment at CERN.

AboutAbout the lab
From building detectors to analyzing data, on site at CERN.
The Okumura Lab conducts experimental research in particle physics.
The lab takes part in the ATLAS experiment, which uses the LHC accelerator at CERN, and searches experimental data for evidence of new laws of nature as part of an international collaboration.
Approaching the subject through the structure of spacetime and the vacuum, and through symmetry, the lab aims to create a new view of nature.
At the same time, the lab operates a large-scale experimental apparatus and develops the technology that will support future experiments.
Key terms
- LHC accelerator
- The world's highest-energy collider, located at CERN. It collides protons head-on with each other.
- Muon trigger
- A system that, out of an enormous number of collisions, instantly selects and records only the important events containing particles called muons.
- Supersymmetric particle
- Particles that have not yet been discovered, predicted by a theory in which every known elementary particle has a partner.

ResearchResearch themes
In the ATLAS experiment at the LHC, a collider at the energy frontier, the lab studies particle reactions with the aim of establishing a new view of nature. The lab works on both technology development for the detectors, electronic circuits, and computers used to collect experimental data, and on data analysis.
*Illustrative imageSearching for new laws of nature in the ATLAS experiment
The lab takes part in the ATLAS experiment and searches particle physics experimental data for evidence of entirely new laws of nature. At the forefront of the field, the lab simultaneously operates the current large-scale apparatus and pioneers the foundational technologies that will support future experiments.
*Illustrative imageDeveloping trigger circuits and searching for new particles
In the master's program, students work on hardware research, such as developing the muon trigger electronic circuit system for the High-Luminosity LHC experiment. In the doctoral program, students spend long periods at CERN and carry out data analysis, such as precision measurements of the Higgs boson and searches for supersymmetric particles.
