Predicting parton energy loss in small collision systems

Understand

Medium induced parton energy loss is not conclusively established neither in very peripheral heavy-ion collisions nor in proton-ion collisions.

• However, the standard interpretation of azimuthal momentum anisotropies in theses systems implies some partonic rescattering.
• The upcoming light-ion runs at the LHC provide a unique opportunity to search for parton energy loss in different systems of similar size.
• Here, we make predictions for the expected parton energy loss signal in the charged hadron spectra in a system size scan at LHC.
