“…In addition, a SUSY µ is insensitive to Yukawa coupling λ because the Singlino field has no mixing with Wino and Bino fields, and it does not couple directly to the muon lepton. As a result, the formulae to calculate a SUSY µ in NMSSM are same as those at the lowest order of the mass-insertion approximation in MSSM [66]. Considering these features, we expected that the Bino-dominated DM case in the Z 3 -NMSSM and MSSM would not show significant differences in explaining the discrepancy.…”

“…• In the case that the DM co-annihilates with Wino-dominated particles to obtain the measured abundance, the Higgsino mass prefers to be much larger than the DM mass, which was explained in Appendix A of this work. In addition, the SUSY contribution to the moment, a SUSY µ , mainly comes from the WHL diagrams after considering the experimental constraints (W , H, and L stand for Wino, Higgsino, and left-handed slepton fields, respectively) [66]. This contribution is proportional to µM 2 tan β/m 2 μL [33], and thus a large |µ| is preferred to predict a sizable a SUSY µ , given that M 2 is relatively small.…”

“…• In the case that the DM co-annihilates with Sleptons to obtain the measured abundance, the LHC's searches for electroweakinos require Higgsinos to be massive because Wino-and Higgsino-dominated electroweakinos can decay into Sleptons and thus enhance the production rate of lepton signals at the LHC [66].…”

“…These features weaken significantly the limitations from the LHC's searches for SUSY. Specifically, in our recent work, we studied a SUSY µ in a simplified version of GNMSSM, which we called µ-extended NMSSM (µNMSSM) [66]. We found that, by presuming the DM and LHC experiments are satisfied, µNMSSM can explain the discrepancy in a broad parameter space where Higgsinos are lighter than about 500 GeV.…”

The General Next-to-Minimal Supersymmetric Standard Model (GN-MSSM) is an attractive theory that is free from the tadpole problem and the domainwall problem of Z 3 -NMSSM, and can form an economic secluded dark matter (DM) sector to naturally predict the DM experimental results. It also provides mechanisms to easily and significantly weaken the constraints from the LHC search for supersymmetric particles. These characteristics enable the theory to explain the recently measured muon anomalous magnetic moment, (g − 2) µ , in a broad parameter space that is consistent with all experimental results and at same time keeps the electroweak symmetry breaking natural. This work focuses on a popular scenario of the GNMSSM in which the next-to-lightest CP-even Higgs boson corresponds to the scalar discovered at the Large Hadron Collider (LHC). Both analytic formulae and a sophisticated numerical study show that in order to predict the scenario without significant tunings of relevant parameters, the Higgsino mass µ tot 500 GeV and tan β 30 are preferred. This character, if combined with the requirement to account for the (g − 2) µ anomaly, will entail some light sparticles and make the LHC constraints very tight. As a result, this scenario can explain the muon anomalous magnetic moment in very narrow corners of its parameter space.

“…Since the new result by the Fermilab has come out, the SUSY interpretation for muon g − 2 anomaly have been discussed in many works . Generally speaking, it is not easy to explain the muon g − 2 anomaly in SUGRA-type models [70][71][72] (unlike the MSSM which can readily give sufficient contributions to the muon g − 2 [67,[73][74][75][76][77]). Large SUSY contributions to ∆a µ in general require light sleptons and light electroweakinos [73,74].…”

Gluino-SUGRA scenarios in light of FNAL muon g – 2 anomaly

Gluino-SUGRA ($$ \overset{\sim }{g} $$ g ~ SUGRA), which is an economical extension of the predictive mSUGRA, adopts much heavier gluino mass parameter than other gauginos mass parameters and universal scalar mass parameter at the unification scale. It can elegantly reconcile the experimental results on the Higgs boson mass, the muon g − 2, the null results in search for supersymmetry at the LHC and the results from B-physics. In this work, we propose several new ways to generate large gaugino hierarchy (i.e. M3 » M1, M2) for $$ \overset{\sim }{g} $$ g ~ SUGRA model building and then discuss in detail the implications of the new muon g − 2 results with the updated LHC constraints on such $$ \overset{\sim }{g} $$ g ~ SUGRA scenarios. We obtain the following observations: (i) for the most interesting M1 = M2 case at the GUT scale with a viable bino-like dark matter, the $$ \overset{\sim }{g} $$ g ~ SUGRA can explain the muon g − 2 anomaly at 1σ level and be consistent with the updated LHC constraints for 6 ≤ M3/M1 ≤ 9 at the GUT scale; (ii) For M1 : M2 = 5 : 1 at the GUT scale with wino-like dark matter, the $$ \overset{\sim }{g} $$ g ~ SUGRA model can explain the muon g − 2 anomaly at 2σ level and be consistent with the updated LHC constraints for 3 ≤ M3/M1 ≤ 3.2 at the GUT scale; (iii) For M1 : M2 = 3 : 2 at the GUT scale with mixed bino-wino dark matter, the $$ \overset{\sim }{g} $$ g ~ SUGRA model can explain the muon g − 2 anomaly at 1σ level and be consistent with the updated LHC constraints for 6.9 ≤ M3/M1 ≤ 7.5 at the GUT scale. Although the choice of heavy gluino will always increase the FT involved, some of the 1σ/2σ survived points of $$ \Delta {a}_{\mu}^{\mathrm{combine}} $$ ∆ a μ combine can still allow low EWFT of order several hundreds and be fairly natural. Constraints from (dimension-five operator induced) proton decay are also discussed.

The new experiment data of muon g − 2 is reported by the workers at Fermilab National Accelerator Laboratory (FNAL). Combined with the previous Brookhaven National Laboratory (BNL) E821 result, the departure from the standard model prediction is about 4.2σ. It strengthens our faith in the new physics. U(1)XSSM is the U(1) extension of the minimal supersymmetric standard model, where we study the electroweak corrections to the anomalous magnetic dipole moment of muon from the one-loop diagrams and some two-loop diagrams possessing important contributions. These two-loop diagrams include Barr-Zee type, rainbow type and diamond type. The virtual supersymmetric particles in these two-loop diagrams are chargino, scalar neutrino, neutralino, scalar lepton, which are supposed not very heavy to make relatively large corrections. We obtain the Wilson coefficients of the dimension 6 operators inducing the anomalous magnetic dipole moment of muon. The numerical results can reach 25 × 10−10 and even larger.
