| contents | After achieving a successful description of charmonia production in proton-proton (pp) collisions within Non-Relativistic Quantum Chromodynamics (NRQCD) and modified NRQCD (MNRQCD) frameworks, we now extend our study to proton-lead (p-Pb) collisions at the Large Hadron Collider (LHC). In this context, theoretical predictions for the production cross-section, the nuclear modification factor $R_{pPb}$ and forward -to-backward production ratio $R_{FB}$ of $J/ψ$ have been made as a function of transverse momentum and rapidity at the LHC. MNRQCD provides a reasonable agreement with the available LHC data for $J/ψ$ production. Furthermore, using the heavy quark symmetry relation, we have estimated the production cross sections and expected number of events of $η_{c}$ and $h_{c}$ production in both NRQCD and MNRQCD. Notably, the predictions exhibit substantial differences in the integrated cross-sections as well as in the $p_T$ distributions for these states at the LHC, highlighting the importance of further experimental and theoretical studies of these resonances to advance our understanding of quarkonium production. |
