Explaining (g − 2) μ with multi-TeV sleptons
Journal of High Energy Physics, 2021 We present a supersymmetric extension of the Standard Model in which the new physics contributions to the anomalous magnetic moment of the muon can be more than an order of magnitude larger than in the minimal supersymmetric Standard Model.

Z(2)-Singlino Dark Matter in a Portal-Like Extension of the Minimal Supersymmetric Standard Model. [PDF]
, 2008 We propose a Z2-stabilized singlino () as a dark matter candidate in extended and R-parity violating versions of the supersymmetric standard model. interacts with visible matter via a heavy messenger field S, which results in a supersymmetric version of ...

Higgs Sector in Extensions of the MSSM [PDF]

THE MINIMAL SUPERSYMMETRIC STANDARD MODEL [PDF]
Modern Physics Letters A, 1996 The structure of the MSSM is reviewed. We first motivate the particle content of the theory by examining the quantum numbers of the known standard model particles and by the requirement of anomaly cancellation. Once the particle content is fixed we can write down the most general renormalizable superpotential.

A minimally fine-tuned supersymmetric standard model [PDF]
Nuclear Physics B, 2005 We construct supersymmetric theories in which the correct scale for electroweak symmetry breaking is obtained without significant fine-tuning. We calculate the fine-tuning parameter for these theories to be at the 20% level, which is significantly better than in conventional supersymmetry breaking scenarios. Supersymmetry breaking occurs at a low scale

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 ...

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.

INFLATION AND THE MINIMAL SUPERSYMMETRIC STANDARD MODEL [PDF]
Modern Physics Letters A, 2008 There is strong evidence from cosmological data that the universe underwent an epoch of superluminal expansion called inflation. A satisfactory embedding of inflation in fundamental physics has been an outstanding problem at the interface of cosmology and high energy physics.

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 ...
