【T. D. Lee Colloquium No. 35】General Standard Model and Hyperunified Field Theory within Gravitational Quantum Field Theory

by Prof. Yueliang Wu (the Institute of Theoretical Physics, CAS)

Thursday 19 Nov 2026, 14:00 → 15:30 Asia/Shanghai

Tsung-Dao Lee Institute/S5F-S500 - Lecture Hall (Tsung-Dao Lee Institute)

Host: Prof. Xiaogang He (何小刚)

Abstract:

The fundamental incompatibility between general relativity and quantum theory (quantum field theory and quantum mechanics) poses a central challenge to developing a unified understanding of physics from quanta to cosmos. Building on the framework of Gravitational Quantum Field Theory (GQFT) that we have proposed and developed, this talk presents the construction of the General Standard Model (GSM) and Hyperunified Field Theory (HUFT), in an effort to provide a unified solution to this problem. This framework offers an entirely new understanding of the nature of gravity and spacetime and profoundly reshapes our fundamental understanding of motion, energy, matter, and the universe. The talk will cover the generalized Dirac equation, the generalized Maxwell equations, and the generalized Einstein equations, as well as the basic structures and central ideas of the GSM and HUFT. It will also present key theoretical predictions concerning the properties of dark matter, the nature of dark energy, the mechanism of cosmic inflation, and new polarization modes of gravitational waves, and discuss the prospects for testing these predictions in future experiments.

Yue-Liang Wu is a theoretical physicist and an Academician of the Chinese Academy of Sciences (CAS). He serves as Chair of the Academic Committee of the Institute of Theoretical Physics, CAS, and Director of the International Centre for Theoretical Physics Asia-Pacific (ICTP-AP), a center under the auspices of UNESCO. He is also Chief Scientist of the Taiji Program for space-based gravitational-wave detection.

He received his bachelor’s degree from Nanjing University in 1982. In 1987, he earned his Ph.D. at the Institute of Theoretical Physics, Chinese Academy of Sciences, with the degree conferred by the University of Chinese Academy of Sciences. From 1987 to 1996, he conducted research in theoretical particle physics and quantum field theory in Germany and the United States. In 1996, he joined the Institute of Theoretical Physics, CAS. His previous appointments include Director of the Institute of Theoretical Physics, CAS; Director of the Kavli Institute for Theoretical Physics China at CAS; Director of the State Key Laboratory of Theoretical Physics; and Executive Vice President of UCAS. He also served as Chief Scientist of the Ministry of Science and Technology’s 973 Program project “Theoretical and Pre-experimental Studies of Dark Matter and Dark Energy.” He has conducted systematic research in particle physics and quantum field theory, gravitational quantum field theory, hyperunified field theory, quanta to cosmos physics, and gravitational-wave physics.
