abstract
We propose to use the theory of phase transitions of Lee and Yang as a practical tool to analyze long-range correlations in a finite-size system. We apply it to the analysis of anisotropic flow in nucleus-nucleus collisions, and show that this method is more reliable than any other used so far.

An MLE analysis on the relationship between the initial-state granularity and final-state flow factorization
Flow factorization, but not differential flow, responds strongly to initial-state granularity in peripheral-tube hydrodynamic simulations, and MLE and cumulant estimators disagree on these correlators.
