Abstract
The cross section of jets reconstructed from charged particles is measured in the transverse momentumrange of5<pT<100GeV=cinppcollisions at the center-of-mass energy offfiffiffisp¼5.02TeV with theALICE detector. The jets are reconstructed using the anti-kTalgorithm with resolution parametersR¼0.2,0.3, 0.4, and 0.6 in the pseudorapidity rangejηj<0.9−R. The charged jet cross sections are comparedwith the leading-order (LO) and to next-to-leading-order (NLO) perturbative quantum chromodynamics(pQCD) calculations. It is found that the NLO calculations agree better with the measurements. The crosssection ratios for different resolution parameters are also measured. These ratios increase from lowpTtohighpTand saturate at highpT, indicating that jet collimation is larger at highpTthan at lowpT. Theseresults provide a precision test of pQCD predictions and serve as a baseline for the measurement in Pb-Pbcollisions at the same energy to quantify the effects of the hot and dense medium created in heavy-ioncollisions at the LHC.
