Abstract
Local density fluctuations near the QCD critical point can be probed by intermittency analysis of scaled factorial moments in relativistic heavy-ion collisions. We report the first measurement of intermittency for charged particles in Au + Au collisions at $\sqrt{s_\mathrm{NN}}$ = 7.7-200 GeV from the STAR experiment at RHIC. We observe scaling behaviors in central Au + Au collisions, with the extracted scaling exponent decreasing from mid-central to the most central Au + Au collisions. Furthermore, the scaling exponent exhibits a non-monotonic energy dependence with a minimum around $\sqrt{s_\mathrm{NN}}$ = 20-30 GeV in central Au + Au collisions.

Report
The authors study intermittency for Charged Particles in Au + Au Collisions at 7.7-200 GeV from STAR collaboration, extracted a non-monotonic energy dependence scaling exponent.
This study is important and and practically useful. The paper reads rather well. I recommend publication. I only offer the following minor comments before publication:
Figure 2 shows \DeltaF_q(M) (q=3-6)… not 2-6.
