Detail description

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

Using 4-particle correlations it is possible to probe the flow magnitude fluctuations separated from the flow angle fluctuations. The two effects are both presents when probing flow vector fluctuations with 2-particle correlations such as with v2{2}/v[2]. Any deviation from the pt-integrated baseline indicates the presence of pt-dependent flow magnitude fluctuations
