Description
The absence of measured high-momentum rescattering (jet quenching) in small collision systems is a long-standing problem in heavy ion physics. Various experimental observables are used to isolate potentially small modifications of high-momentum observables in peripheral lead-lead and proton-lead collisions relative to proton-proton collisions at the LHC. The planned oxygen-oxygen and potential neon-neon collisions at the LHC also offer unique experimental and theoretical opportunities to study energy loss in small systems. The discovery of energy loss in small systems crucially relies on the comparison to the proton-proton data. However, even in the absence of partonic rescattering, the high-momentum observables differ in nuclear and proton collisions due to the differences in the nuclear and proton parton distribution functions. Correctly accounting for nPDF uncertainties is crucial for precisely measuring jet quenching in small systems. In this talk, I will present several baseline calculations of inclusive and semi-inclusive observables in small systems and highlight the constraints the nPDF uncertainties put on the energy loss measurements.
