$r_2$ at $\sqrt{s_{NN}} = 5.02$ TeV with $|\Delta\eta| > 0.8$ and $0.2 < \textit{p}_T^t < 0.6$. The errors bars correspond to statistical uncertainties while the shaded color bands correspond to systematic uncertainties. Hydrodynamc calculations with TRENTo and AMPT initial conditions are shown in magenta and yellow.

The factorization ratio r2 to probe pT-dependent flow vector fluctuations in Pb-Pb collisions. Values smaller than unity indicate that factorization is broken, meaning the two-particle correlation does not factorize into the product of a function of properties of only one of the particles times a function of the
properties of the second.
