Probing charmonia resonances in proton-lead collisions at the LHC

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.

Predictions for $h_c$ and $h_b$ production at the LHC

The production cross sections of $h_c$ and $h_b$, the ${}^1P_1$ quarkonia can be predicted in Non-Relativistic Quantum Chromodynamics (NRQCD) using heavy quark symmetry. Our study includes predictions for both the integrated cross-section and the transverse momentum ($p_T$) distribution of $h_c$ ($h_b$) production at the Large Hadron Collider (LHC), using the decay process $h_c (h_b) \rightarrow η_c (η_b) + γ$, $η_c (η_b) \rightarrow p \overline{p}$. We demonstrate substaintial discrepancies in integrated cross-section and the $p_T$ distribution of ${}^1P_1$ quarkonia production at the LHC using Colour-Singlet Model (CSM), NRQCD and modified NRQCD. Measuring these resonances at the LHC could discriminate between these models, thereby offering further insights into the dynamics of quarkonium production. In addition, we compare the recent LHCb data for the integrated cross-section of $h_c$ production at $\sqrt{s}$ = 13 TeV in the kinematic range 5.0 $<$ $p_T$ $<$ 20.0 GeV and 2.0 $<$ $y$ $<$ 4.0 with the theoretical predictions using NRQCD and modified NRQCD. Modified NRQCD gives an agreement with the recent LHCb experimental data.

Bottomonia production in Modified NRQCD

Motivated by the success of Modified Non-Relativistic Quantum Chromodynamics (Modified NRQCD) in explaining data from experiments at the Large Hadron Collider (LHC) for charmonia, we now turn to the study of bottomonium production at the LHC. Modified NRQCD does very well in explaining $Υ$ data from the LHC. But this is true also of NRQCD which explains the $Υ$ data equally well. Where the two models differ substantially is in their predictions for $η_b$ production. As was the case with $η_c$, the measurement of $η_b$ production at the LHC will be another decisive test of Modified NRQCD.
