Several problems on the measured hyperorder cumulants of net-proton distributions in heavy-ion collisions Open
Hyperorder cumulants $C_5/C_1$ and $C_6/C_2$ are recommended as sensitive observables to explore the QCD phase transition in heavy-ion collisions. Precisely measuring their results remains a difficult task in experiments, when employing th…

Identifying weak critical fluctuations of intermittency in heavy-ion collisions with topological machine learning Open
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 expected to exhibit a fractal or scale-invariant behavior, whi…

Impact of limited statistics on the measured hyperorder cumulants of net-proton distributions in heavy-ion collisions Open
Hyperorder cumulants ${C}_{5}/{C}_{1}$ and ${C}_{6}/{C}_{2}$ of net-baryon distributions are anticipated to offer crucial insights into the phase transition from quark-gluon plasma to hadronic matter in heavy-ion collisions. However, the a…

Investigations into the characteristics and influences of nonequilibrium evolution Open
In order to estimate qualitatively the influence of nonequilibrium evolution in relativistic heavy ion collisions, we use the three dimensional Ising model with Metropolis algorithm to study the evolution from nonequilibrium to equilibrium…

Intermittency analysis of proton numbers in heavy-ion collisions at energies available at the BNL Relativistic Heavy Ion Collider Open
Local density fluctuations near the QCD critical point has been suggested to\nexhibit a power-law behavior which can be probed by an intermittency analysis\non scaled factorial moment (SFM) in relativistic heavy-ion collisions. The\ncollis…

Measurement methods of radial flow in relativistic heavy-ion collisions Open
Radial flow can be directly extracted from the azimuthal distribution of mean transverse rapidity. We apply the event-plane method and the two-particle correlation method to estimate the anisotropic Fourier coefficient of the azimuthal dis…

Fine structures of azimuthal correlations of two gluons in the glasma Open
We investigate the azimuthal correlations of the glasma in p-p collisions at $\sqrt{s_{\mathrm{NN}}}=7$ TeV by using the CGC formalism. As expected, the azimuthal correlations show two peaks at $\Delta\phi=0$ and $\pi$ which represent coll…
