Left: detector response matrix of matched jets used for unfolding zch || distribution with R = 0.4 in pp collisions at √s = 5.02 TeV in the range 2 < pT,ch jet < 50 GeV/c and 0.4 < zch || < 1. Right: zch || resolution, ∆z, in the zch,part || intervals 0.4–0.6, 0.6–0.8, and 0.8–1 for the pT,ch jet interval 5 < ppart T,ch jet < 7 GeV/c
