The production cross sections of hc and hb, the ¹P₁ 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 (pT) distribution of hc (hb) production at the Large Hadron Collider (LHC), using the decay process hc (hb) → ηc (ηb) + γ, ηc (ηb) → p p̄. We demonstrate substaintial discrepancies in integrated cross-section and the pT distribution of ¹P₁ 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.
