“…Moreover, we assume the A 1 to be produced via the decay of a heavy scalar Higgs boson of the model, the latter induced by gg fusion. (As finally established in [2], although some scope was demonstrated for single A 1 production in association with a b b prior to LHC Higgs data [3], this channel no longer carries any promise. Also, note that the scope of Vector Boson Fusion (VBF) and Higgs-strahlung is also currently being re-assessed in the light of the same experimental results [4].)…”

“…Assuming the same production process, it was established in [28] that an A 1 , with 20 GeV m A 1 80 GeV, could be observed with very large luminosity at the LHC in the b b decay channel. This is made possible by an enhanced coupling of A 1 to b b pairs for certain configurations of the model parameters [29]. b b-associated production also affords the possibility to search for the H SM → A 1 Z decay mode [30], where H SM is our notation for the generic SM-like Higgs boson of the model.…”

The Next-to-Minimal Supersymmetric Standard Model (NMSSM) contains a singlet-like pseudoscalar Higgs boson in addition to the doublet-like pseudoscalar of the Minimal Supersymmetric Standard Model. This new pseudoscalar can have a very low mass without violating the LEP exclusion constraints and it can potentially provide a hallmark signature of non-minimal supersymmetry at the LHC. In this analysis we revisit the light pseudoscalar in the NMSSM with partial universality at some high unification scale. We delineate the regions of the model's parameter space that are consistent with the up-to-date theoretical and experimental constraints, from both Higgs boson searches and elsewhere (most notably $b$-physics), and examine to what extent they can be probed by the LHC. To this end we review the most important production channels of such a Higgs state and assess the scope of its observation at the forthcoming Run-2 of the LHC. We conclude that the $b\bar{b}$-associated production of the pseudoscalar, which has been emphasised in previous studies, does not carry much promise anymore, given the measured mass of the Higgs boson at the LHC. However, the decays of one of the heavier scalar Higgsbosons of the NMSSM can potentially lead to the discovery of its light pseudoscalar. Especially promising are the decays of one or both of the two lightest scalar states into a pseudoscalar pair and of the heaviest scalar into a pseudoscalar and a $Z$ boson. Since the latter channel has not been explored in detail in the literature so far, we provide details of some benchmark points which can be probed for establishing its signature.Comment: 33 pages, 13 figures.

“…Nevertheless, there is regions of the parameter space where the very high values of tan β (above 30) are compatible with the current theoretical and experimental constraints. For these large values of tan β, the Higgs production in association with a b-quark pair is dominant and become the best production mode for producing the NMSSM Higgs bosons at the LHC [46][47][48][49][50][51]. The ratio of the decays…”

In this paper, we present the branching ratios of the two lightest CP-even Higgses, h 1 and h 2 , and of the lightest CP-odd Higgs, a 1 , in the context of the Non-Minimal Supersymmetric Standard Model (NMSSM). We find that for some regions of the parameter space, the branching fractions of a 1 into the lightest charginos (a 1 → χ + 1 χ − 1 ) and neutralinos (a 1 → χ 0 1 χ 0 1 ) are larger than 50%, and can reach a 100% level in the latter case. Furthermore, the branching ratio of the h 2 → a 1 a 1 can be equal to unity for all masses of h 2 when it is a pure singlet. The above unusual channels are hallmarks of the existence of the NMSSM.

“…There have been some studies exploring the production potential of the NMSSM CPodd Higgs states at the LHC and other colliders [25][26][27][28][29][30][31][32][33][34][35][36][37][38][39]. It was found that the best direct production channel of producing the lightest CP-odd Higgs state a 1 is through its production in association with a bottom antibottom pair b ba 1 .…”

In this paper we examine the LHC discovery potential of the lightest CP-odd Higgs boson, a 1 , of the NMSSM produced in gluon fusion channel gg → a 1 . We evaluate the inclusive signal rates of the a 1 for a variety of decay channels and discuss its possible discovery. It is observed that the overall production and decay rates at inclusive level are quite sizable and should help extracting the a 1 signal over some regions of the NMSSM parameter space.
