Muon g−2 and dark matter in the minimal supersymmetric standard model

Physical Review D, 2018
We investigate the possibility that both dark matter and the long-standing discrepancy in the anomalous magnetic moment of the muon may be explained within the MSSM. In light of the stringent bounds from direct detection, we argue that the most promising

Higgs Scalars in the Minimal Non-minimal Supersymmetric Standard Model [PDF]

, 2000
We consider the simplest and most economic version among the proposed non-minimal supersymmetric models, in which the $\mu$-parameter is promoted to a singlet superfield, whose all self-couplings are absent from the renormalizable superpotential.

Supersymmetric Higgs singlet effects on FCNC observables [PDF]

, 2008
Higgs singlet superfields, usually present in extensions of the Minimal Supersymmetric Standard Model (MSSM) which address the $\mu$-problem, such as the Next-to-Minimal Supersymmetric Standard Model (NMSSM) and the Minimal Nonminimal Supersymmetric ...

The Higgs mass bound in gauge extensions of the minimal supersymmetric standard model [PDF]

, 2003
The minimal supersymmetric standard model, and extensions, have stringent upper bounds on the mass of the lightest Higgs boson if perturbativity up to the Planck scale is assumed.

Strong Sector in non-minimal SUSY model

EPJ Web of Conferences, 2016
We investigate the squark sector of a supersymmetric theory with an extended Higgs sector. We give the mass matrices of stop and sbottom, comparing the Minimal Supersymmetric Standard Model (MSSM) case and the non-minimal case.

Relic density of dark matter in the next-to-minimal supersymmetric standard model [PDF]

, 2005
We present a code for computing the relic density of dark matter in the next-to-minimal supersymmetric standard model (NMSSM). Dominant corrections to the Higgs masses are calculated with NMHDECAY as well as theoretical and collider constraints.

Towards TeV-scale supersymmetric electroweak baryogenesis

Journal of High Energy Physics, 2023
Electroweak baryogenesis (EWBG) offers a compelling narrative for the generation of the baryon asymmetry, however it cannot be realised in the Standard Model, and leads to severe experimental tensions in the Minimal Supersymmetric Standard Model (MSSM ...

Dark matter, constrained minimal supersymmetric standard model, and lattice QCD. [PDF]

Physical Review Letters, 2009
Recent lattice measurements have given accurate estimates of the quark condensates in the proton. We use these results to significantly improve the dark matter predictions in benchmark models within the constrained minimal supersymmetric standard model ...
