Properties of Full Jet in High-Energy Heavy-Ion Collisions from Parton Scatterings

Figure 7

The jet fragmentation function ratios of four centrality bins in Pb + Pb collisions to p + p collisions. The solid curves show two-component (fragmentation + coalescence) fitting functions, while the two kinds of hatched areas give the fragmentation and coalescence contribution parts, that is, and , for the jet fragmentation function ratios measured by the CMS experiment [14].

(a) 0–10%/p + p

(b) 10–30%/p + p

(c) 30–50%/p + p

(d) 50–100%/p + p
