### Description

A multi-dimensional analysis of prompt charmonia in pp and pPb collisions at 5.02 TeV with the CMS detector is presented. The pPb differential cross-sections of prompt J/$\psi$ are shown in a wide kinematic region, for transverse momentum p$_T$ spanning from 2 to 30 GeV/c and a rapidity interval between -2.87 to 1.93 in the center of mass of the collision. The ratio of yields in forward (p-going beam) and backward (Pb-going beam) directions, R$_{\mathrm{FB}}$, is measured, to quantify the asymmetry of cross-sections as a function of p$_T$, rapidity, and event activity. A significant asymmetry is observed for \$2
