Description

Overview:

The workshop on frontier of theoretical particle physics and gravity is jointly organized by Sichuan University and Institute for Basic Science Center for Theoretical Physics of the Universe – Cosmology, Gravity and Astroparticle Physics Group – (IBS CTPU-CGA) on May 24-27, 2026, including registration day, at Chengdu.

Particle physics and cosmology are increasingly interconnected, jointly addressing fundamental questions about the origin, structure, and evolution of the Universe. To advance understanding in these areas and promote interdisciplinary exchange, we organize an international workshop focused on the frontiers of particle physics phenomenology and gravity.

The conference will bring together leading researchers to present and discuss recent progress in key topics, including dark matter and dark energy, neutrino, flavor physics and searches for physics beyond the Standard Model, collider physics, cosmological theory and observations using multi-messenger data (such as CMB, large-scale surveys, and gravitational waves), and fundamental aspects of gravity and spacetime.

Time:

May 24-27, 2026 (24th is for registration and free discussion)
