The 5th workshop of Symmetry and Structure of the Universe (SSU 2026 Busan) is to be held at Lavalse Hotel, Yeongdo, Busan on Aug 23 - 27, 2026. The workshop aims to cover the present status and recent issues of high energy physics and cosmology, and so to establish close collaborations for probing the fundamental symmetries and the structure of the Universe. A broad range of topics including collider phenomenology, dark matter, neutrino physics, early universe cosmology and astroparticle physics will be extensively covered and intensively discussed.
There is no registration fee. Accommodation at Lavalse Hotel during the workshop (check-in on Aug 23, check-out on Aug 27) will be provided for invited speakers and graduate students. Other participants can also stay at the hotel at a discounted rate. If you would like the organizing committee to arrange your hotel reservation, please indicate your check-in and check-out dates during registration.
SSU 2026 Busan is generously supported by IBS-CTPU-PTC, Jeonbuk National University, and Pusan National University.
The registration period is July 6 (Mon) – July 14 (Tue). Please note that abstract submissions and additional talk requests cannot be accommodated. As the number of hotel rooms is limited, registration may close before the deadline once the available rooms are fully booked. We encourage you to register as early as possible.
SSU 2026 Busan is preceded by 12th Workshop on Flavor Symmetries and Consequences in Accelerators and Cosmology (FLASY 2026) on Aug 17 - 22 at Gyeongju which is just about an hour distance by car.
