$r_3$ at $\sqrt{s_{NN}} = 5.02$ TeV with $|\Delta\eta| > 0.8$ for different trigger particle $\textit{p}_T^t$. The errors bars correspond to statistical uncertainties while the shaded color bands correspond to systematic uncertainties.










Detail description

Keywords: Flow, Flow vector fluctuations, pT-dependent flow vector fluctuations, Pb-Pb collisions, 5.02 TeV

The factorization ratio r3 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.
