Welcome to the 2025 CERN-CKC joint workshop with the 13th KIAS Workshop on Particle Physics and Cosmology. We are planning to bring together a mix of theorists working on all aspects of beyond the standard model physics. We plan a program with ample time for discussions. The total number of participants will be limited to around 60 (plus students) to ensure informality.
