About SI2026

Welcome to the 30th International Summer Institute on the Phenomenology of Elementary Particle Physics and Cosmology (SI2026), which will be held from August 7–13, 2026, at the foot of Mt. Fuji!
The Summer Institute series has been held every summer since 1995.

The purpose of the Summer Institute is to foster communication and discussion among participants on current research, rather than to provide pedagogical lectures for students. Accordingly, the scientific program is deliberately kept relaxed to allow ample time for interaction. We hope that new ideas and research collaborations will be inspired by this institute!
