Abstract
Local density fluctuations near the QCD critical point can be probed by an intermittency analysis of power-law behavior on scaled factorial moments in relativistic heavy-ion collisions. We study the second-order scaled factorial moment in Au + Au collisions at $\sqrt{s_\mathrm{NN}}$ = 7.7-200 GeV from the UrQMD model. Since the background subtraction and efficiency correction are two important aspects in this measurement, we propose a cumulative variable method to remove background contribution and a cell-by-cell method for efficiency correction in the intermittency analysis.

Report
A study of the intermittency in Au + Au collisions using the UrQMD model is presented. Improvements are implementing leading to results that could give a guidance to background subtraction and efficiency correction for the intermittency analysis in heavy-ion experiments.
