29. A scenario for electroweak baryogenesis in 2HDM

Shinya Kanemura (Osaka University)

Plenary Talk

We discuss a two Higgs doublet model with successful electroweak baryogenesis but without cancellations of electric dipole moments (EDMs). For the baryogenesis, additional scalar bosons are favored to couple mainly with the top quark with CP violations. However, if they also couple to light fermions of the Standard Model, the model is limited severely by EDMs, and additional CP phases...

56. Overview of recent progress in PandaX experiment

Plenary Talk

PandaX ( Particle and Astrophysical Xenon experiment), a large-scale liquid xenon dark matter detection project located at the China Jinping Underground Laboratory, has provided a high-sensitivity experimental platform for dark matter searches through the iterative development of three generations of detectors since its launch in 2009. It adopts the two-phase xenon time projection chamber...

31. Search for the QCD Critical Point and Strange Di-baryon in High Energy Nuclear Collisions

Xiaofeng Luo (Central China Normal University)

Plenary Talk

Understanding the properties of quark matter and its phase structure is crucial for advancing our knowledge of the universe's evolution and the composition of visible matter. Over the past two decades, numerous experimental observations have provided evidence for the existence of strongly interacting quark-gluon plasma (sQGP) in relativistic heavy-ion collisions. As a result, exploring the QCD...

36. Parity-Violation with Electrons: The Standard Model and Beyond

Michael Ramsey-Musolf (TDLI-SJTU)

Plenary Talk

Measurements of parity-violating observables in electron scattering, atomic transitions, and electron-positron annihilation have played a decisive role in confirming and testing the Standard Model electroweak sector and in probing the strong interaction in the non-perturbative regime. After reviewing this story, I discuss the experimental frontier for parity-violation with electrons and the...

39. From the V-A theory of weak interaction to the uniqueness of the standard model and beyond

Chao-Qiang Geng (Hangzhou Institute for Advanced Study, UCAS)

Plenary Talk

Parity conservation was first questioned along with some possible experimental tests suggested by TD Lee and CN Yang in 1956. In 1957, several experiments confirmed parity nonconservation in weak interaction. However, the theory of weak interaction: V-A theory was only established in 1958 by Marshak et al. The V-A chiral structure is encoded as the defining feature of the electroweak unified...
