Center for Theoretical Physics of the Universe

Research Areas of CTPU

Given the lack of convincing guidance from experiments, probing Beyond the Standard Model (BSM) physics requires cooperative research efforts over a wide range of topics in fundamental physics. Therefore, many of our activities are based on multidisciplinary approaches to particle physics and cosmology. The broad spectrum of research backgrounds represented by our group members enables us to carry out a comprehensive scientific program and make significant contributions to the outstanding problems in BSM physics.

Although it is not officially structured, the Particle Theory and Early-Universe Cosmology group can be categorized into three subgroups: a subgroup aligned with particle physics interests, another with astro-particle physics and early-Universe cosmology, and the other with string phenomenology. This division is not strict, as it is defined merely by the research interests of members. In particular, each member can join multiple subgroups and freely move from one subgroup to another. Each subgroup also internally manages a weekly working-group meeting on different days, which is designed to promote collaborations among the group members.
