“…Due to the clean signature, the associated productions of heavy quarkonium and standard model (SM) bosons are ideal channels to test the NRQCD, which have been attracted more and more attention. The hadronic productions of heavy quarkonium associated with γ, W ± , Z and Higgs boson have been studied at leading order (LO) within NRQCD [1,[37][38][39], and the next-to-leading order (NLO) QCD corrections for the productions of heavy quarkonium associated with γ, W ± , Z have been calculated in Refs. [40][41][42][43][44].…”

The production of charmonium associated with Higgs boson via gluon fusion has been investigated in Ref. [1], in which they considered the contribution of final Higgs boson radiation off the charm quark at tree level and found that this process is to be far too rare to be observable in any of the considered experiments. In this paper, the production of prompt J/ψ associated with Higgs boson via gluon fusion at the 14 TeV LHC within the factorization formalism of NRQCD is revisited. After considering the contribution from the final Higgs boson radiation off the top quark in the loop, which is more than three orders of magnitudes over the charm quark at tree level, the production of prompt J/ψ associated with Higgs boson has great potential to be detected. The prompt J/ψ production includes the direct production and indirect production via radiative or hadronic decays of high excited charmonium states. For the direct J/ψ + H production via gluon fusion loop-induced, the 3 S (8) 1Fock state gives dominant contribution to the cross section, which is about 95% to the total direct production. The indirect contribution via loop-induced is appreciable, since the summation of which from ψ(2S) + H, χc1 + H and χc2 + H is about 34% to the total cross section of prompt J/ψ + H. While the indirect contribution from χc0 + H is tiny, which can be neglected. With the great potential to be detected, prompt J/ψ production in associated with Higgs boson can help us to further understand the mechanism of colour-octet, as well as can be useful to further investigate the coupling of the Higgs boson and fermion.

“…being made to obtain improved theoretical predictions for complementary observables to the inclusive yield, such as hadroproduction of J/ψ and Υ (thereafter commonly named Q) in association with a photon [19,20,21,22,23,24,25,26]. Recently, the NLO corrections to the hadroproduction of Q + γ in the CS channel were computed by Li and Wang in [27].…”

We update the study of the QCD corrections to direct J/ψ and Υ hadroproduction in association with a photon in the QCDbased approach of the Colour-Singlet (CS) Model. After comparison with the recent full next-to-leading-order (NLO) computation for this process, we provide an independent confirmation to the inclusive case that NLO QCD corrections to quarkonium-production processes whose LO exhibits a non-leading P T behaviour can be reliably computed at mid and large P T by considering only the real emission contributions accompanied with a kinematical cut. In turn, we evaluate the leading part of the α 4 S α contributions, namely those coming from (J/ψ, Υ) + γ associated with two light partons. We find that they are dominant at mid and large P T . This confirms our expectations from the leading P T scaling of the new topologies appearing at NNLO. We obtain that the yield from the CS becomes one order of magnitude larger than the upper value of the potential Colour-Octet yield. The polarisation of the 3 S 1 quarkonia produced in association with a photon is confirmed to be longitudinal at mid and large P T .
