“…[1] for the direct production of J/ψ + H and χ cJ + H, and obtain consistent results of the transverse momentum and rapidity distribution. Adopting the same input parameters, we obtain the total cross section of J/ψ production in associated with Higgs boson via gluon fusion at the 14 TeV LHC is about 0.02 fb, which is agree with the results shown in their another work [51]. One can see that, in this case it is difficult to detect this process at the LHC.…”

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.

“…[90], there are contributions from resonant electroweak production from q q, production from gg in association with a g, γ, or Z, and deexcitation of gg-produced P -wave states. Production from gg in association with the Higgs is forbidden by charge conjugation invariance (as known for SM quarkonia [106,107]).…”

In scenarios that stabilize the electroweak scale, the top quark is typically accompanied by partner particles. In this work, we demonstrate how extended stabilizing symmetries can yield scalar or fermionic top partners that transform as ordinary color triplets but carry exotic electric charges. We refer to these scenarios as "hypertwisted" since they involve modifications to hypercharge in the top sector. As proofs of principle, we construct two hypertwisted scenarios: a supersymmetric construction with spin-0 top partners, and a composite Higgs construction with spin-1/2 top partners. In both cases, the top partners are still phenomenologically compatible with the mass range motivated by weak-scale naturalness. The phenomenology of hypertwisted scenarios is diverse, since the lifetimes and decay modes of the top partners are model dependent. The novel coupling structure opens up search channels that do not typically arise in top-partner scenarios, such as pair production of top-plus-jet resonances. Furthermore, hypertwisted top partners are typically sufficiently long lived to form "top-partnerium" bound states that decay predominantly via annihilation, motivating searches for rare narrow resonances with diboson decay modes.

We present a simple method to automatically evaluate arbitrary tree-level amplitudes involving the production or decay of a heavy quark pair QQ in a generic 2S+1 L [1,8] J state, i.e., the short distance coefficients appearing in the NRQCD factorization formalism. Our approach is based on extracting the relevant contributions from the open heavy quark-antiquark amplitudes through an expansion with respect to the quark-antiquark relative momentum and the application of suitable color and spin projectors. To illustrate the capabilities of the method and its implementation in MadGraph a few applications to quarkonium collider phenomenology are presented.
