Understanding the Intermittency Signal in RHIC-STAR Data through Modeling
Jin Wu, Zhiming Li, Mingmei Xu +3
Intermittency analysis provides a promising probe of scale-invariant density fluctuations near the QCD critical point. The intermittency measurements reported in the STAR BES-I dat…
Model Study of Eigen-Microstate Signatures of Criticality in Relativistic Heavy-Ion Collisions
Ranran Guo, Jin Wu, Mingmei Xu +8
We present a comprehensive model study of the eigen-microstate approach (EMA) for identifying critical fluctuations in relativistic heavy-ion collisions. Using UrQMD and two stocha…
Eigen-microstate Signatures of Criticality in Relativistic Heavy-Ion Collisions
Ranran Guo, Jin Wu, Mingmei Xu +4
We develop the eigen-microstate framework as a new approach to identify criticality in relativistic heavy-ion collisions. We construct the original microstate, defined as the final…
Identifying weak critical fluctuations of intermittency in heavy-ion collisions with topological machine learning
Rui Wang, Chengrui Qiu, Chuan-Shen Hu +2
Large density fluctuations of conserved charges have been proposed as a promising signature for exploring the QCD critical point in heavy-ion collisions. These fluctuations are exp…
Exploring percolation phase transition in the three-dimensional Ising model with machine learning
Ranran Guo, Xiaobing Li, Rui Wang +3
The percolation study offers valuable insights into the characteristics of phase transition, shedding light on the underlying mechanisms that govern the formation of global connect…
Several problems on the measured hyperorder cumulants of net-proton distributions in heavy-ion collisions
Lizhu Chen, Ye-Yin Zhao, Zhiming Li +1
Hyperorder cumulants and are recommended as sensitive observables to explore the QCD phase transition in heavy-ion collisions. Precisely measuring their results…
