We test the impact of the ATLAS and CMS multi-lepton searches performed at the LHC with 8 as well as 13 TeV center-of-mass energy (using only the pre-2018 results) on the chargino and neutralino sector of the NMSSM. Our purpose consists in analyzing the actual reach of these searches for a full model and in emphasizing effects beyond the MSSM that affect the performance of current (MSSM-inspired) electroweakino searches. To this end, we consider several scenarios characterizing specific…

Revisiting singlino dark matter of the natural Z3-symmetric NMSSM in the light of LHC
Abstract Inspired by the fact that relatively small values of the effective higgsino mass parameter of the Z 3-symmetric Next-to-Minimal Supersymmetric Standard Model (NMSSM) could render the
Dark matter in the CP-violating NMSSM
In the Next-to-Minimal Supersymmetric Standard Model there is a strong correlation between the mass terms corresponding to the singlet Higgs and the singlino interaction states, both of which are
Impact of recent (g − 2)μ measurement on the light CP-even Higgs scenario in general Next-to-Minimal Supersymmetric Standard Model
The General Next-to-Minimal Supersymmetric Standard Model (GNMSSM) is an attractive theory that is free from the tadpole problem and the domain-wall problem of Z 3 -NMSSM, and can form an economic
Electroweak corrections to the fermionic decays of heavy Higgs states
Extensions of the standard model often come with additional, possibly electroweakly charged Higgs states, the prototypal example being the Two-Higgs-Doublet Model. While collider phenomenology does
Light higgsino-dominated NLSPs in semi-constrained NMSSM
In the semi-constrained NMSSM (scNMSSM, or NMSSM with non-universal Higgs mass) under current constraints, we consider a scenario where $h_2$ is the SM-like Higgs, $\tilde{\chi}^0_1$ is
A relatively light, highly bino-like dark matter in the Z3-symmetric NMSSM and recent LHC searches
A highly bino-like Dark Matter (DM), which is the Lightest Supersymmetric Particle (LSP), could be motivated by the stringent upper bounds on the DM direct detection rates. This is especially so when
Improved $(g-2)_\mu$ measurement and singlino dark matter in $\mu$-term extended $\mathbb{Z}_3$-NMSSM
Very recently, a Fermilab report of muon g − 2 showed a 4.2σ discrepancy between it and the standard model (SM) prediction. Motivated by this inspiring result and the increasing tension in
Current bounds and future prospects of light neutralino dark matter in the NMSSM
Unlike its minimal counterpart, the Next to Minimal supersymmetric Standard Model (NMSSM) allows the possibility that the lightest neutralino could have a mass as small as $\sim 1~{\rm GeV}$ while
Phenomenology of scotogenic scalar dark matter
We reexamine the minimal Singlet + Triplet Scotogenic Model, where dark matter is the mediator of neutrino mass generation. We assume it to be a scalar WIMP, whose stability follows from the same
