The study of isolated heavy quarkonia, such as [Formula: see text] and [Formula: see text], produced in association with a photon in proton-proton collisions at the LHC, is probably the optimal way to get right away a first experimental determination of two gluon transverse-momentum-dependent distribution (TMDs) in an unpolarized proton, [Formula: see text] and [Formula: see text], the latter giving the distribution of linearly polarized gluons. To substantiante this, we calculate the transverse-momentum-dependent effects that arise in the process under study and discuss the feasibility of their measurements.

The transverse momentum spectra of [Formula: see text] mesons, protons and antiprotons produced in proton–proton collisions at 200 GeV with hadron production models are reported. Two tunes of EPOS (EPOS1.99 and EPOS-LHC), three tunes of QGSJET (QGSJETI, QGSJETII-03, QGSJETII-04), DPMJET and HIJING models are used to obtain the spectra. The results are compared with the measurements of STAR collaboration obtained at mid-rapidity of [Formula: see text] in [Formula: see text] range of [Formula: see text]. All models reproduce the ratios [Formula: see text] and [Formula: see text] at low [Formula: see text] but could not predict well at high [Formula: see text]. In addition, EPOS tunes and QGSJET tunes predict well the spectra of [Formula: see text] meson and the ratios [Formula: see text] and [Formula: see text] at low [Formula: see text]. The HIJING and the QGSJET (tune I only) could reproduce all the spectra and all the ratios at a satisfactory level of precision and were found good among the models considered in the current study at RHIC energy.
