18. Observation of Strong Directed Flow for $\phi$ Mesons in the High-Baryon-Density Region at RHIC

Guangyu Zheng (University of Chinese Academy of Sciences)

Directed flow $v_1$ has been used to probe the early dynamics in high-energy nuclear collisions. The vector meson $\phi(s\bar{s})$, with a mass comparable to that of light baryons and weak hadronic interactions, provides a unique probe of the interplay between particle production mechanisms and early-stage dynamics in high-density nuclear matter.

In this talk, we report measurements of...

41. D0-Ds+ Elliptic-Flow Splitting under Event-Shape Engineering: A Probe of Sequential Charm Hadronization

Recent work has proposed sequential hadronization of open-charm hadrons in the quark-gluon plasma, wherein more tightly bound species such as Ds+ form earlier near 1.2Tc and D0 forms later at Tc. That work showed that this mechanism naturally reverses the sign of the D0 − Ds+ elliptic-flow splitting ∆v2 ≡ v2(D0) − v2(Ds+) relative to the conventional simultaneous baseline. In this work, we...

20. Third-body-corrected Two-Pion Femtoscopic Correlations in Au+Au Collisions at high baryon density

Youquan Qi (Central China Normal University)

Measurements of identical pion femtoscopy offer insights into collision dynamics, such as collective expansion, geometry of the collision zone at freeze-out, final state interactions, etc. In addition to the quantum interference and Coulomb interactions among the pion pairs, Coulomb interactions between the pair and the net positive charge in the emitting source affect the final correlation...

42. An Infrared Topological Approach to Baryon Structure

Fan Lin (Anhui University of Science and Technology)

19/10/2026, 17:30

This report investigates the infrared structure of QCD through the lens of the Cho–Faddeev–Niemi decomposition and Faddeev–Niemi effective theory. We argue that gluon knots, as topological solitons characterized by the Hopf invariant, constitute the relevant infrared ground-state degrees of freedom of Yang–Mills fields. Within this framework, we present a unified mechanism for monopole...
