Figure Caption
Comparison of near-side associated yield and width, for D-meson - charged particle correlations, in p-Pb collisions at sqrt(sNN) = 5.02 TeV in three different ZNA centrality ranges (0-20%, 20-60%, 60-100%). Results are presented as a function of the pT(D), in 3 different ranges of pT(assoc).
Fit function: double Gaussian + constant pedestal (from weighted average of the points in pi/4 < |deltaPhi| < pi/2).
Fit applied to average of D0, D+, D*+ correlation distributions, with D mesons in -0.96 < y^D_cms < 0.04 and charged particles in |eta|<0.8.
Correlations are shown for |∆η| < 1 only.
Statistical uncertainties are shown as error bars, systematic uncertainties as error boxes, uncertainty from non-zero v2Delta hypothesis is plotted as filled boxes.
Only primary pions, kaons, protons, electrons and muons are correlated to D-mesons.
