The flow angle decorrelation F(\Psi_2^a,\Psi_2) with |\Delta\eta| > 0.0 in Pb-Pb collisions at \sqrt{s_{NN}} = 5.02 TeV 

 
 
 
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 angle fluctuations separated from the flow magnitude fluctuations. The two effects are both presents when probing flow vector fluctuations with 2-particle correlations such as with v2{2}/v[2]
