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.
