Abstract：
CP violation (CPV) is one of the three conditions for the matter-antimatter asymmetry in the Universe. The visible matter primarily consists of baryons. Nevertheless, despite observations of CPV in mesons over several decades, experimental evidence for CPV in baryon decays remains elusive. This raises important questions: Why is the CPV in baryons less pronounced than in mesons? What processes are most promising for detecting baryon CPV? In this talk, I will discuss the recent progresses on these questions. It has been found that the partial-wave-amplitude CPV tends to cancel each other, leading to the small total CPV of baryons. Furthermore, a new CPV mechanism has been proposed, which involves final-state N\pi rescatterings in the decays of heavy-flavor baryons. It predicts the CPV that are sufficiently large for observation using the current LHCb data.
Biography:：
Fu-Sheng Yu is a professor of theoretical particle physics at Lanzhou University. He got his Ph.D. degree from the Institute of High Energy Physics, Chinese Academy of Science, in 2013. Then he joined the School of Nuclear Science and Technology at Lanzhou University. His research primarily focuses on heavy flavor physics. He made significant contributions to the prediction on the discovery channel of double-charm baryon, and to the understanding of CP violation in charm physics. His current interests include exploring baryon CP violation and developing novel theoretical approach to non-perturbative QCD.
