Description
J/$\psi$ mesons have long been proposed as ideal probes capable of providing evidences of the formation of Quark--Gluon Plasma (QGP) in ultra-relativistic heavy-ion collisions. Various Cold Nuclear Matter (CNM) effects are however expected to affect J/$\psi$ production in addition to the modifications due to the presence of the QGP, and the study of p--Pb collisions represents a crucial tool to assess the influence of CNM on J/$\psi$ production.
From the analysis of LHC Run 1 data (2009-2013), ALICE produced measurements of J/$\psi$ production in p--Pb collisions at mid-rapidity down to zero transverse momentum ($p_{\rm T}$). The statistical separation of the non-prompt J/$\psi$ component resulting from beauty-hadron decays has also been performed down to $p_{\rm T}$ = 1.3 GeV/$c$, allowing an evaluation of nuclear effects also on beauty quark production. Data of p--Pb collisions with J/$\psi$ produced at mid-rapidity have been subsequently made available during LHC Run 2 data taking campaign (2015-2018), granting a six-fold increase in luminosity and allowing more precise measurements to be performed.
In this poster, ALICE results for the production of prompt and non-prompt J/$\psi$ in p--Pb collisions at mid-rapidity will be presented. The status of analyses for the measurement of J/$\psi$ production on the Run 2 data sample will also be reported.
