New Physics in the Dark Universe 2026

Oct 27, 2026, 9:00 AM → Oct 28, 2026, 5:00 PM Asia/Tokyo

K206 (YITP)

Particle physics and cosmology have become increasingly interconnected in recent years. In particular, understanding the origin and nature of dark matter is one of the central challenges both in the search for new physics beyond the Standard Model and in understanding the formation and evolution of the Universe. A wide range of approaches are being pursued, including theoretical studies, accelerator experiments, underground experiments, and astronomical observations.

This workshop will bring together researchers working in particle physics, cosmology, dark matter, and related fields to share recent developments and promote interdisciplinary discussions. Particular emphasis will be placed on the connections between particle physics models and cosmological and astronomical observations, as well as on the complementarity among theoretical, experimental, and observational approaches to dark matter searches. The workshop aims to explore new directions for future research and to foster potential collaborations across different fields.
