c→uγ in the minimal supersymmetric standard model [PDF]
Physics Letters B, 2001 The minimal supersymmetric standard model (MSSM) with universal soft breaking terms has a negligible effect on the rare $c\to u\gamma$ decay rate. We therefore study a general model with non-universal soft breaking terms constrained by vacuum stability and the experimental upper bound on the mass difference of the neutral charm mesons.

Constrained Next-to-Minimal Supersymmetric Standard Model [PDF]
Physical Review Letters, 2008 We consider the fully constrained version of the next-to-minimal supersymmetric extension of the standard model (cNMSSM) in which a singlet Higgs superfield is added to the two doublets that are present in the minimal extension (MSSM). Assuming universal boundary conditions at a high scale for the soft supersymmetry-breaking gaugino, sfermion and Higgs

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

Gravitational waves from domain walls in the next-to-minimal supersymmetric standard model [PDF]
, 2015 The next-to-minimal supersymmetric standard model predicts the formation of domain walls due to the spontaneous breaking of the discrete Z3-symmetry at the electroweak phase transition, and they collapse before the epoch of big bang nucleosynthesis if ...

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.

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 ...
