NSC($3,2_{p_T}$) and NSC($4,2_{p_T}$) at $\sqrt{s_{NN}} = 5.02$ TeV. 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 light red/blue and dark red/blue respectively.





Detail description

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

The normalized single-differential symmetric cumulant to probe flow magnitude fluctuations. The NSC(n,m_pt) does not depend on flow angle and thus contains information about the flow magnitude fluctuations only.

Data sample: LHC15o

Events cuts: kInt7 trigger,  |Vz| < 10cm, V0M centrality estimator, Pileup cut, 

Track cuts: Filterbit 96, No. of TPC cluster > 70, NUA weights, Reference pT [0.2,5.0], |eta| < 0.8
