Description
Prompt photon production is known as a powerful tool for testing perturbative QCD predictions and also the validity of parton densities in the nucleon and nuclei especially of the gluon. In this talk, we are going to discuss the impact of input nuclear modifications obtained from different global analyses by various groups on the isolated prompt photon production in p-Pb collisions at forward rapidity at the LHC. We show that future measurements with ALICE will be very useful not only for decreasing the uncertainty of the gluon nuclear modification, but also to accurately determine its central values, especially in the shadowing region.
