Measurements of charged jet production as a function of centrality are presented for p–Pb collisions recorded at √sNN = 5.02 TeV with the ALICE detector. Cen- trality classes are determined via the energy deposit in neu- tron calorimeters at zero degree, close to the beam direction, to minimise dynamical biases of the selection. The corre- sponding number of participants or binary nucleon–nucleon collisions is determined based on the particle production in the Pb-going rapidity region. Jets have been reconstructed in the central rapidity region from charged particles with the anti-kT algorithm for resolution parameters R = 0.2 and R = 0.4 in the transverse momentum range 20 to 120 GeV/c. The reconstructed jet momentum and yields have been cor- rected for detector effects and underlying-event background. In the five centrality bins considered, the charged jet pro- duction in p–Pb collisions is consistent with the produc- tion expected from binary scaling from pp collisions. The ratio of jet yields reconstructed with the two different reso- lution parameters is also independent of the centrality selec- tion, demonstrating the absence of major modifications of the radial jet structure in the reported centrality classes.
