Figure 10

Jet R_AA as a function of p_T for three centrality bins: 0–1% (red circles), 10–20% (blue squares) and 40–50% (green diamonds). Each panel indicates a different range in |y|: | y | < 2.1 (top), 0.3 < | y | < 0.8 (middle) and 1.2 < |y| < 2.1 (bottom). The fractional uncertainties from the luminosity and the ⟨ T_AA ⟩ factors are indicated separately as a shaded box centered at one. The boxes indicate the uncertainties due to the unfolding and are partially correlated in p_T. The remaining uncertainties are fully correlated in p_T and are indicated by shaded regions.

Jet R_AA as a function of p_T in the |y| < 2.1 range for the 0–10% centrality interval. The fractional luminosity and ⟨ T_AA ⟩ uncertainties are indicated separately as a shaded box centered at one. The boxes, bands and error bars indicate uncorrelated systematic, correlated systematic and statistical uncertainties, respectively. The data were fit to the form R_AA=a ln (p_T/ 100 GeV) + b, with the correlations in the uncertainties among the different p_T bins accounted for in the fit procedure. Values of a=0.11±0.04 and b=0.42±0.02 were obtained, and the fits, including uncertainty on a and b are indicated by the green hatched area.

The blue hatched region indicates the results of the calculation varying the value of jet-medium coupling, g_med, from 2.0 to 2.1.
