“…The Higgs decays widths and branching ratios are obtained from NMHDECAY [26], an NMSSM extension of the Fortran code HDECAY [46,47]. The SUSY particle branching ratios are obtained from the Fortran code NMSDECAY [48] which is a generalisation of the Fortran code SDECAY [47,49] to the NMSSM particle spectrum. The NMSSM particle spectrum, mixing angles, decay widths and branching ratios are given out in the SUSY Les Houches Accord (SLHA) format [50].…”

We investigate the discovery prospects for NMSSM Higgs bosons during the 13 TeV run of the LHC. While one of the neutral Higgs bosons is demanded to have a mass around 125 GeV and Standard Model (SM)-like properties, there can be substantially lighter, nearby or heavier Higgs bosons, that have not been excluded yet by LEP, Tevatron or the 8 TeV run of the LHC. The challenge consists in discovering the whole NMSSM Higgs mass spectrum. We present the rates for production and subsequent decay of the neutral NMSSM Higgs bosons in the most promising final states and discuss their possible discovery. The prospects for pinning down the Higgs sector of the Natural NMSSM will be analysed taking into account alternative search channels. We give a series of benchmark scenarios compatible with the experimental constraints, that feature Higgs-to-Higgs decays and entail (exotic) signatures with multi-fermion and/or multi-photon final states. These decay chains furthermore give access to the trilinear Higgs self-couplings. We briefly discuss the possibility of exploiting coupling sum rules in case not all the NMSSM Higgs bosons are discovered.

“…In table 1, we show the two benchmark parameter sets in the two distinct parameter regions which exemplify the small λ and the large λ regions, respectively. In our analysis, we use the spectrum calculator NMSSMTools 4.7.0 [26,27] and also use the decay width calculator NMSDECAY [28]. In the table, we also show the properties of the dark matter which are calculated using MicrOMEGAs4.1.8 [29,30] (see next section).…”

Recently the ATLAS experiment has reported 3.0 σ excess in an on-Z signal region in searches for supersymmetric particles. We find that the next-to-minimal supersymmetric standard model can explain this excess by the production of gluinos which mainly decay viag → gχ 0 2,3 → gZχ 0 1 whereχ 0 2,3 andχ 0 1 are the Higgsino and the singlinolike neutralinos, respectively. We show that the observed dark matter density is explained by the thermal relic density of the singlino-like neutralino, simultaneously. We also discuss the searches for the Higgs sector of this scenario at the Large Hadron Collider.

We study a class of realizations of the Next-to-Minimal Supersymmetric Standard Model that is motivated by dark matter and Higgs data, and in which the lightest pseudoscalar Higgs boson mass is smaller than twice the bottom quark mass and greater than twice the tau lepton mass. In such scenarios, the lightest pseudoscalar Higgs boson can be copiously produced at the LHC from the decay of heavier superpartners and will dominantly further decay into a pair of tau leptons that is generally boosted. We make use of a boosted object tagging technique designed to tag such a ditau jet, and estimate the sensitivity of the LHC to the considered supersymmetric scenarios with 20 to 50 fb −1 of proton-proton collisions at a center-of-mass energy of 13 TeV.
