About me:
Wenbin Zhao currently is a postdoc in Wayne State University and Brookhaven National Laboratoy since 2021. He received his Ph.D degree at Peking University in 2020, and worked as a Research Assistant in Central China Normal University in 2020-2021. His research interests cover some areas of the heavy-ion collisions and the Electron-Ion Collider. Such as the collectivity on the large and small systems, hadronization mechanisms, light nuclei productions in heavy-ion collisions, and diffractive processes at the Electron-Ion Collider.
Seminar Title:
What is the baryon charge number carrier? Where is the limit of hydrodynamics? (Investigation on the Baryon Junction and the Collectivity)
Seminar Date:
Feb. 7th, 2023
Abstract:
In this talk, I will present our recent work about the (3+1)D hydrodynamics simulations in Ultra-Peripheral Pb+Pb collisions (UPCs) at LHC and small system scan at RHIC. For UPC simulations, we find longitudinal flow decorrelation can explain the smaller 𝑣2 in 𝛾*+Pb collisions and compared to those in p+Pb collisions. For RHIC small system scan, we find a big fraction of 𝑣3 (𝑝𝑇) difference in STAR and PHENIX measurements can be explained by using reference flow vectors from different rapidity regions. We also study the baryon junction mechanism in UPCs. UPCs provide a clean channel to probe initial-state baryon stopping dynamics.
