Detail description

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

The ratio of v3{2} and v3[2] to probe pT-dependent flow vector fluctuations in Pb-Pb collisions. v2{2} has contribution from pT-dependent flow vector fluctuations as well as non-flow, whereas v2[2] only has contribution from non-flow.

Data sample: LHC15o
