“…(iii) Supersymmetry frameworks. These include minimal supersymmetric SM (MSSM) [39][40][41], vectorlike extended MSSM [42,43], and the minimal R-symmetric supersymmetric SM (MRSSM) [44]. 3 Among these frameworks, supersymmetry (SUSY) explanations are quite naturally applied to account for Δa μ because they introduce an additional supersymmetric contribution a SUSY μ to a μ , which is generically given as follows [45].…”

The present work investigates the possibility that both dark matter and the anomalous magnetic moment of the muon may be explained within the context of the inverse seesaw extended next-to-minimal supersymmetric Standard Model (ISS-NMSSM). In ISS-NMSSM, the newly introduced Higgs-neutrino Yukawa coupling Y ν provides additional Higgsino-sneutrino loop contribution to ðg − 2Þ μ. If the deviation between the experimental observations and the Standard Model predictions of the anomalous muon magnetic moment is confirmed by the further experimental and theoretical studies, it can be explained naturally within the ISS-NMSSM framework without conflicting with the current stringent limits on the direct detection of dark matter and Large Hadron Collider searches.

“…In this case again, the scenario of figure 16 with very large µ is the only option to obtain significant a SUSY µ [174,181,184,224]. We mention that the scenario with µ in the multi-TeV region is also important to obtain large a SUSY µ in the context of various specific model constructions, such as models based on Pati-Salam symmetry [194] (here, at the same time light Winos are preferred), models with usual GUT constraints but extra vectorlike matter fields [200,216], and in a hybrid gauge-gravity mediation model with only four free parameters [206].…”

The Fermilab Muon g −2 experiment recently reported its first measurement of the anomalous magnetic moment $$ {a}_{\mu}^{\mathrm{FNAL}} $$ a μ FNAL , which is in full agreement with the previous BNL measurement and pushes the world average deviation $$ \Delta {a}_{\mu}^{2021} $$ ∆ a μ 2021 from the Standard Model to a significance of 4.2σ. Here we provide an extensive survey of its impact on beyond the Standard Model physics. We use state-of-the-art calculations and a sophisticated set of tools to make predictions for aμ, dark matter and LHC searches in a wide range of simple models with up to three new fields, that represent some of the few ways that large ∆aμ can be explained. In addition for the particularly well motivated Minimal Supersymmetric Standard Model, we exhaustively cover the scenarios where large ∆aμ can be explained while simultaneously satisfying all relevant data from other experiments. Generally, the aμ result can only be explained by rather small masses and/or large couplings and enhanced chirality flips, which can lead to conflicts with limits from LHC and dark matter experiments. Our results show that the new measurement excludes a large number of models and provides crucial constraints on others. Two-Higgs doublet and leptoquark models provide viable explanations of aμ only in specific versions and in specific parameter ranges. Among all models with up to three fields, only models with chirality enhancements can accommodate aμ and dark matter simultaneously. The MSSM can simultaneously explain aμ and dark matter for Bino-like LSP in several coannihilation regions. Allowing under abundance of the dark matter relic density, the Higgsino- and particularly Wino-like LSP scenarios become promising explanations of the aμ result.

“…The results are presented in terms of number of observed events in the 3l + E / T channel in each SR and the corresponding number of SM backgrounds (see Table 13 and 14 of [16]) extracted from the data. With these two numbers one can obtain the model independent upper bound on N BSM for each SR [62]. We have used this information to constrain the pMSSMs discussed in the last section.…”

The aim of this paper is to showcase the novel multilepton (nl + E /T , n = 3 -5) signals, hitherto unexplored at the LHC, arising from the heavier electroweakinos, in several generic pMSSMs at the upcoming LHC experiments. We first briefly review our old constraints on the full electroweakino sector of these models, containing both lighter and heavier sparticles, using the ATLAS trilepton data from the LHC Run I. Next we derive new stronger constraints on this sector for the first time using the ATLAS Run II data. We identify some benchmark points and explore the prospect of observing multilepton events in future LHC experiments. Our focus is on the channels with n > 3 which are the hallmarks of the heavier electroweakinos. If the spectrum of the lighter electroweakinos is compressed, these signals might very well be the discovery channels of the electroweakinos at the high luminosity LHC. We also discuss the implications of the new LHC constraints for the observed dark matter relic density of the universe, the measured value of the anomalous magnetic moment of the muon and the dark matter direct detection experiments.
