“…5 When the SUSY scale is very large, additional checks on the value of m h are required at low tan β, for which a comparison with an effective field theory calculation is necessary. Results of such an analysis [47,48] indicate that, even in such heavy-M SU SY scenarios, the predictions of the hMSSM agree within a few percent with the exact results for m H , α and λ Hhh , as long as the condition µX t /M 2 SU SY 1 is satisfied. For the purposes of our N = 2 study here, which is restricted to the Higgs sector, we follow the philosophy proposed in [42][43][44][45][46], in which the hMSSM scenario was introduced to discuss the N = 1 MSSM Higgs sector.…”

We explore the possibility that physics at the TeV scale possesses approximate N = 2 supersymmetry, which is reduced to the N = 1 minimal supersymmetric extension of the Standard Model (MSSM) at the electroweak scale. This doubling of supersymmetry modifies the Higgs sector of the theory, with consequences for the masses, mixings and couplings of the MSSM Higgs bosons, whose phenomenological consequences we explore in this paper. The mass of the lightest neutral Higgs boson h is independent of tan β at the tree level, and the decoupling limit is realized whatever the values of the heavy Higgs boson masses. Radiative corrections to the top quark and stop squarks dominate over those due to particles in N = 2 gauge multiplets. We assume that these radiative corrections fix m h 125 GeV, whatever the masses of the other neutral Higgs bosons H, A, a scenario that we term the h2MSSM. Since the H, A bosons decouple from the W and Z bosons in the h2MSSM at tree level, only the LHC constraints on H, A and H ± couplings to fermions are applicable. These and the indirect constraints from LHC measurements of h couplings are consistent with m A 200 GeV for tan β ∈ (2, 8) in the h2MSSM.

“…[14][15][16][17][18][19][20]. Similarly, also a general Two-Higgs-Doublet-Model was already considered as low energy limit of the MSSM [21][22][23]. Finally, since several years Split-SUSY variants of the MSSM have become more and more popular in which the coloured SUSY particles are integrated out [15][16][17][24][25][26].…”

For a long time, the minimal supersymmetric standard model (MSSM) with light masses for the supersymmetric states was considered as the most natural extension of the Standard Model of particle physics. Consequently, a valid approximation was to match the MSSM to the precision measurement directly at the electroweak scale. This approach was also utilized by all dedicated spectrum generators for the MSSM. However, the higher the supersymmetric (SUSY) scale is, the bigger the uncertainties which are introduced by this matching. We point out important consequences of a two-scale matching, where the running parameters within the SM are calculated at M Z and evaluated up to the SUSY scale, where they are matched to the full model. We show the impact on gauge coupling unification as well as the SUSY mass spectrum. Also the Higgs mass prediction for large supersymmetric masses has been improved by performing the calculation within an effective SM. The approach presented here is now also available in the spectrum generator SPheno. Moreover, also SARAH was extended accordingly and gives the possibility to study these effects now in many different supersymmetric models.

“…(Here we use α f = (Y f ) 2 /(4π), with Y f denoting the fermion Yukawa coupling.) These corrections, together with a resummation of leading and subleading logarithms from the top/scalar top sector [40] (see also [41,42] for more details on this type of approach), a resummation of leading contributions from the bottom/scalar bottom sector [38,39,[43][44][45][46] (see also [47,48]) and momentum-dependent two-loop contributions [49,50] (see also [51]) are included in the public code FeynHiggs [32,40,[52][53][54][55][56][57][58]. A (nearly) full two-loop EP calculation, including even the leading three-loop corrections, has also been published [59,60], which is, however, not publicly available as a computer code.…”

Precise prediction for the Higgs-boson masses in the $$\mu \nu $$ μ ν SSM

The μνSSM is a simple supersymmetric extension of the Standard Model (SM) capable of predicting neutrino physics in agreement with experiment. In this paper we perform the complete one-loop renormalization of the neutral scalar sector of the μνSSM with one generation of right-handed neutrinos in a mixed on-shell/DR scheme. The renormalization procedure is discussed in detail, emphasizing conceptual differences to the minimal (MSSM) and next-to-minimal (NMSSM) supersymmetric standard model regarding the field renormalization and the treatment of nonflavor-diagonal soft mass parameters, which have their origin in the breaking of R-parity in the μνSSM. We calculate the full one-loop corrections to the neutral scalar masses of the μνSSM. The one-loop contributions are supplemented by available MSSM higher-order corrections. We obtain numerical results for a SM-like Higgs boson mass consistent with experimental bounds. We compare our results to predictions in the NMSSM to obtain a measure for the significance of genuine μνSSM-like contributions. We only find minor corrections due to the smallness of the neutrino Yukawa couplings, indicating that the Higgs boson mass calculations in the μνSSM are at the same level of accuracy as in the NMSSM. Finally we show that the μνSSM can accomodate a Higgs boson that could explain an excess of γ γ events at ∼ 96 GeV as reported by CMS, as well as the 2 σ excess of bb events observed at LEP at a similar mass scale.
