ALICE measurements of inclusive (top) and leading (bottom) subjet zr distributions in pp collisions at √s = 5.02 TeV, compared to NLL′ predictions carried out with SCET [46, 47] and corrected for missing neutral-particle energy and multi-parton interaction effects using PYTHIA8 [62] or HERWIG7 [78]. The shaded bands denote systematic uncertainty on the NLL′ calculations. The distributions are normalized such that the integral of the region defined by 0.7 < zr < zNP r is unity, where zNP r is denoted by the dashed vertical blue lines. The non-
perturbative scale in Eq. 4 is taken to be Λ = 1 GeV/c. In determining the normalization, bins that overlap with the dashed blue line are considered to be in the non-perturbative (right) region.
