Strength of Forward-backward event-mean transverse momenta correlations (bcorr) in Pb-Pb collisions at 2.76 TeV  in comparison with HIJING and AMPT (3 tunes) as a function of centrality (by V0M)

 

Detail description

Strength of Forward-backward event-mean transverse momenta correlations (bcorr) in Pb-Pb collisions at 2.76 TeV in comparison with AMPT, as a function of centrality. Centrality classes of 2% width for data (by V0M), of 10% width in HIJING (by reco V0M), and of 5% in AMPT (using multiplicity in V0 acceptance for AMPT, which was split into quantiles).

Dashed blue line - for HIJING. Green dashed line is for AMPT (LHC13f3c, kine-level, string melting ON, rescattering ON), pink line for string melting ON, rescattering OFF, orange line for string melting OFF, rescattering ON. 

FB windows ηgap=0.8, window width δη=0.4, pT range 0.2-2.0 GeV/c. Data points: rectangles represent systematic uncertainties, statistical errors are shown as vertical bars and usually are of the similar size as the marker.
