Welcome to the Homepage of Nanjo Group, Department of Physics, Osaka University

We are a High Energy Physics research group, which uses accelerators to research on particle symmetries.
Check out the experiments we work on here.

High Energy Physics Experiments we work on

KOTO Detector
The purpose of J-PARC KOTO experiment is to search for new physics beyond the standard model, that break CP symmetry. CP is a symmetry between matter and anti-matter. We are using CP-violating rare Kaon decay as a probe.

The KOTO Experiment located in JPARC, Japan

ATLAS Detector
The Osaka ATLAS group is working on the ATLAS experiment using the Large Hadron Collider (LHC) at the European Nuclear Research Organization, CERN (Geneva). We are studying the properties of the Higgs particle and searching for new particles predicted by various theories beyond the standard model. We are also developing silicon detectors for the future upgrade of the ATLAS detector.

The ATLAS Experiment located in CERN, Switzerland
