Measurement methods of radial flow in relativistic heavy-ion collisions
Peng Yang, Lin Li, Yu Zhou +4
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 estima…
The method of mixed events for higher cumulants of conserved charges
Fan Zhang, Zhiming Li, Lizhu Chen +5
Higher cumulants of conserved charges are sensitive observables of quantum chromodynamics phase transitions. The sample of mixed events provides a background to estimate non-critic…
Subtracting non-critical fluctuations in higher cumulants of conserved charges
Fan Zhang, Zhiming Li, Lizhu Chen +5
Using the sample produced by the AMPT default model, we construct a corresponding mixed sample by the method of mixed events. The mixed sample provides an effective estimation for…
Locating fixed points in the phase plane
Yanhua Zhang, Ye-Yin Zhao, Lizhu Chen +5
The critical point is a fixed point in finite-size scaling. To quantify the behaviour of such a fixed point, we define, at a given temperature and scaling exponent ratio, the width…
