Fully-Reconstructed Jet Invariant Cross Sections and R_pPb at √s_NN = 8 TeV Using the ALICE Detector

Measurements in small systems such as pp and p–Pb collisions are important in order to provide constraints on nuclear PDFs and disentangle initial and final state effects, including cold nuclear matter effects and modifications due to the presence of a medium in heavy ion collisions. While such a medium is not expected in small collision systems, recent studies still suggest the presence of collectivity. The fully-reconstructed jet invariant cross sections and nuclear modification factor (R_pPb) for different jet radii are presented from measurements using the ALICE detector at the CERN LHC in pp collisions at √s = 8 TeV and p–Pb collisions at √s_NN = 8.16 TeV. For this analysis, jets are reconstructed using charged tracks from the Time Projection Chamber (TPC) and the Inner Tracking System (ITS), and neutral constituents from clusters in the Electromagnetic Calorimeter (EMCal).
