Description
Proton-nucleus collisions are utilized to distinguish between initial and final state effects, which is vital for establishing a baseline for heavy-ion collisions. One of the crucial reference measurements is the jet nuclear modification factor ($R_{\rm pPb}$) in p-Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV at the LHC.
Jets in ALICE are reconstructed using the anti-k$_{\rm T}$ jet finding algorithm combining information from the Time Projection Chamber (TPC), Inner Tracking System, and the Electromagnetic Calorimeter (EMCal) to measure the charged and neutral jet constituents.
In this poster, we discuss in detail the systematic uncertainties on the jet energy scale using the TPC and EMCal in ALICE. Furthermore various techniques to estimate the underlying event in p-Pb collisions will be presented. The jet cross-section and the ratios of jet cross-sections for various radii, sensitive to the jet shape, will be compared to pp and pQCD calculations.
