As part of the Nagoya University MIRAI GSC project, we supervised Mr. Taichi Saito (Gifu High School, Gifu Prefecture) and Mr. Kota Ishimori (Handa High School, Aichi Prefecture) from July 29th to August 2nd, 2024. Through experiments to measure the lifetime of muons, lectures, tours of equipments, and discussions with graduate students, they gained knowledge and skills in particle physics experiments.

In the lectures on particle physics, they learned particle physics extensivery, from theory to experiment. In the experiment to measure the lifetime of muons, they considered and discussed how to measure the target quantity, built a data collection system, and obtained the data. Additionally, by analysing the data using an open-source analysis framework ROOT, they successfully measured the lifetime of muons. They toured the particle identification device for the Belle II experiment and the new circuitry for the ATLAS experiment, both of which have been developed in our laboratory.

From the measured muon lifetime, they concluded that the muon decays via the weak interaction, one of the four fundamental interactions in nature. It was a worthwhile experience for those involved in guiding the project.
