Description
Local density fluctuation near the QCD critical point has been suggested to exhibit a power-law behavior which can be probed by an intermittency analysis on scaled factorial moment in relativistic heavy-ion collisions.
In this talk, I will review recent work on the search for power-law fluctuations with fractality and intermittency analysis in heavy-ion collisions. Experimental measurement from STAR, NA49 and NA61 collaborations[1-3] on self-similar correlations and fluctuations with respect to the size of phase space volume in various high energy collisions are presented, with special emphasis on background subtraction and efficiency correction of the measurement. Phenomenological modelling and theoretical work on the subject are discussed[4-7]. Finally, I will highlight possible directions for future research[8].
