The Present and Future of QCD
P. Achenbach, D. Adhikari, A. Afanasev +400
This White Paper presents the community inputs and scientific conclusions from the Hot and Cold QCD Town Meeting that took place September 23-25, 2022 at MIT, as part of the Nuclea…
Pattern of Global Spin Alignment of and mesons in Heavy-Ion Collisions
STAR Collaboration, M. S. Abdallah, B. E. Aboona +379
Notwithstanding decades of progress since Yukawa first developed a description of the force between nucleons in terms of meson exchange, a full understanding of the strong interact…
Little-Bang and Femto-Nova in Nucleus-Nucleus Collisions
Kenji Fukushima, Bedangadas Mohanty, Nu Xu
We make a theoretical and experimental summary of the state-of-the-art status of hot and dense QCD matter studies on selected topics. We review the Beam Energy Scan program for the…
Sequential hadronization in heavy ion collisions
Jiaxing Zhao, Shuzhe Shi, Nu Xu +1
Heavy flavor supplies a chance to constrain and improve the hadronization mechanism. We have established a sequential coalescence model with charm conservation and applied it to th…
Freeze-out and thermalization in relativistic heavy ion collisions
Sourendu Gupta, Debasish Mallick, Dipak Kumar Mishra +2
High energy heavy-ion collisions in laboratory produce a form of matter that can test Quantum Chromodynamics (QCD), the theory of strong interactions, at high temperatures. One of…
Sequential Coalescence with Charm Conservation in High Energy Nuclear Collisions
Jiaxing Zhao, Shuzhe Shi, Nu Xu +1
Heavy quarks are initially produced in nuclear collisions and the number is conserved during the evolution of the system. We establish a sequential coalescence model with charm con…
Resonance decay effect on conserved number fluctuations in a hadron resonance gas model
D. K. Mishra, P. Garg, P. K. Netrakanti +1
We study the effect of charged secondaries coming from resonance decay on the net-baryon, net-charge and net-strangeness fluctuations in high energy heavy-ion collisions within the…
Heavy Quark and Quarkonium Transport in High Energy Nuclear Collisions
Kai Zhou, Wei Dai, Nu Xu +1
The strong interaction between heavy quarks and the quark gluon plasma makes the open and hidden charm hadrons be sensitive probes of the deconfinement phase transition in high ene…
Magnetic Field Effect on Charmonium Production in High Energy Nuclear Collisions
Xingyu Guo, Shuzhe Shi, Nu Xu +2
It is important to understand the strong external magnetic field generated at the very beginning of high energy nuclear collisions. We study the effect of the magnetic field on the…
Υ Production in Heavy Ion Collisions at LHC
Kai Zhou, Nu Xu, Pengfei Zhuang
We investigate the Υ production in heavy ion collisions at LHC energy in the frame of a dynamical transport approach. Both the initial production and in-medium regeneration and bot…
Baseline measures for net-proton distributions in high energy heavy-ion collisions
P. K. Netrakanti, X. F. Luo, D. K. Mishra +3
We report a systematic comparison of the recently measured cumulants of the net-proton distributions for 0-5\% central Au+Au collisions in the first phase of the Beam Energy Scan (…
Scale for the Phase Diagram of Quantum Chromodynamics
Sourendu Gupta, Xiaofeng Luo, Bedangadas Mohanty +2
Matter described by Quantum Chromodynamics (QCD), the theory of strong interactions, may undergo phase transitions when its temperature and the chemical potentials are varied. QCD…
Phi meson production at RHIC
L. Bravina, L. Csernai, Amand Faessler +4
The production of phi mesons in Au+Au collisions at RHIC and their propagation in a hot and dense nuclear medium is studied within the microscopic quark-gluon string model. The inv…
Recent results from heavy ion collisions
Nu Xu
Systematic trends of baryon transport, chemical freeze-out, and kinetic freeze-out in high energy nuclear collisions are presented. Further measurements of particles with heavy fla…
Strangeness enhancement from strong color fields at RHIC
M. Bleicher, W. Greiner, H. Stöcker +1
In ultra-relativistic heavy ion collisions, early stage multiple scatterings may lead to an increase of the color electric field strength. Consequently, particle production - espec…
Global observables and secondary interactions in central Au+Au reactions at AGeV
M. Bleicher, S. A. Bass, L. V. Bravina +5
The Ultra-relativistic Quantum Molecular Dynamics model (UrQMD) is used to study global observables in central reactions of Au+Au at AGeV (RHIC). Strong stopping gov…
