### Description

Relativistic heavy-ion collisions are the unique tool to study the properties of the deconfined state of quarks and gluons, Quark-Gluon Plasma (QGP). Dissociation of J/$\psi$ is thought as one of the strong evidences of QGP formation. At LHC energy, regeneration of J/$\psi$ from thermalized charm quarks is also expected to be pronounced.
In order to discuss the QGP effects in relativistic heavy-ion collisions, the understanding of cold nuclear matter effects such as gluon shadowing, gluon saturation, and nuclear absorption is crucial.
Proton--nucleus collisions are suited for the study of the cold nuclear matter effects.
Furthermore, the charged particle multiplicity dependence of J/$\psi$ production provides an insight on the underlying physics such as Multi-Parton Interactions (MPI).
p--Pb collisions were recorded in 2016 with the ALICE detector at the LHC. In this poster, we will show the status of J/$\psi$ analysis in p--Pb collisions which includes the centrality dependence of the nuclear modification factor ($R_{\rm{pPb}}$, $Q_{\rm{pPb}}$) and the charged particle multiplicity dependence of J/$\psi$ yield.
