On March 19, 2025, the F9 department organized the fifth consecutive international masterclass on particle physics, attended by approximately 65 high school students from all over Slovenia. During the morning lectures, participants were introduced to the basics of particle physics, medical physics, and the detectors used in research. During the break, they explored the Belle II detector in virtual reality.
Afterward, they split into three workshops to gain further insight into the analytical methods used by researchers. In the first two workshops, they searched for unknown short-lived particles using data collected by the ATLAS and Belle II detectors, while in the third workshop, they used radiotherapy simulation to select an irradiation plan that would effectively suppress tumor growth.
Finally, the students presented their results via videoconference to participants from other research institutes, which were conducting the masterclass simultaneously.
