“…(4.9) and (4.10) are never fulfilled. However, one could increase the value ofλ 3 by augmenting the MSSM with either a singlet scalar, as in the case of NMSSM [71][72][73][74][75][76][77][78][79][80][81], or a triplet scalar [34,35]. In these models, a gauge singlet, S, in the case of NMSSM, and a triplet scalar, Σ, in the case of triplet augmented MSSM, are added to the superpotential with the following cubic couplings, among others,…”

In models with an extended Higgs sector there exists an alignment limit, in which the lightest CP-even Higgs boson mimics the Standard Model Higgs. The alignment limit is commonly associated with the decoupling limit, where all non-standard scalars are significantly heavier than the Z boson. However, alignment can occur irrespective of the mass scale of the rest of the Higgs sector. In this work we discuss the general conditions that lead to "alignment without decoupling", therefore allowing for the existence of additional non-standard Higgs bosons at the weak scale. The values of tan β for which this happens are derived in terms of the effective Higgs quartic couplings in general twoHiggs-doublet models as well as in supersymmetric theories, including the MSSM and the NMSSM. Moreover, we study the information encoded in the variations of the SM Higgsfermion couplings to explore regions in the m A − tan β parameter space.

“…Note that the two effects that we highlighted -uplift of the mass of the SM-like state via its mixing with the singlet and presence of a 'miniature' Higgs boson under 125 GeV -are well-known in the CP-conserving NMSSM [11][12][13][14][15][16][17][18], provided the auxiliary singlet is CP-even. CP-violation extends this possibility to CP-odd singlets.…”

“…The Next-to-Minimal Supersymmetric Standard Model (NMSSM), a singlet-extension of the simplest viable SUSY-inspired extension of the SM [10], has raised renewed interest ever since the Higgs discovery, notably due to its properties in the Higgs sector, e.g. allowing for an uplift of the mass of the SM-like Higgs related to F-terms or to the mixing of this state with a lighter singlet [11][12][13][14][15][16][17][18]. The original motivation for this singlet extension rests with the 'µ-problem' of the MSSM [19], which can be solved elegantly if this µ-term is generated dynamically, via a singlet vacuum expectation value (v.e.v.)…”

Supersymmetric extensions of the Standard Model open up the possibility for new types of CP-violation. We consider the case of the Next-to-Minimal Supersymmetric Standard Model where, beyond the phases from the soft lagrangian, CP-violation could enter the Higgs sector directly at tree-level through complex parameters in the superpotential. We develop a series of Fortran subroutines, cast within the public tool NMSSMTools and allowing for a phenomenological analysis of the CP-violating NMSSM. This new tool performs the computation of the masses and couplings of the various new physics states in this model: leading corrections to the sparticle masses are included; the precision for the Higgs masses and couplings reaches the full one-loop and leading two-loop order. The two-body Higgs and top decays are also attended. We use the public tools HiggsBounds and HiggsSignals to test the Higgs sector. Additional subroutines check the viability of the sparticle spectrum in view of LEP-limits and constrain the phases of the model via a confrontation to the experimentally measured Electric Dipole Moments. These tools will be made publicly available in the near future. In this paper, we detail the workings of our code and illustrate its use via a comparison with existing results. We also consider some consequences of CP-violation for the NMSSM Higgs sector.

We analyze the Higgs-boson masses and mixing matrices in the NMSSM based on an on-shell (OS) renormalization of the gauge-boson and Higgs-boson masses and the parameters of the top/scalar top sector. We compare the implementation of the OS calculations in the codes NMSSM-CALC and NMSSM-FeynHiggs up to O(α t α s ). We identify the sources of discrepancies at the one-and at the twoloop level. Finally we compare the OS and DR evaluation as implemented in NMSSMCALC. The results are important ingredients for an estimate of the theoretical precision of Higgs-boson mass calculations in the NMSSM.
