Various Cold Nuclear Matter (CNM) effects, such as nuclear shadowing or partonic energy loss, can modify the production of J/ψ in heavy-ion collisions with respect to what is measured in elementary colliding systems. The study of p-Pb collisions at the Large Hadron Collider (LHC) energy scale represents a crucial tool to assess the influence of Cold Nuclear Matter on J/ψ production in order to achieve a more correct interpretation of Pb-Pb collision results. The ALICE detector at the LHC is

In this paper, the results obtained by ALICE from the measurement of the prompt and non-prompt J/ψ yields at mid-rapidity in p-Pb collisions at √ s NN = 5.02 TeV will be discussed in comparison to different theoretical predictions including CNM effects.
