Standard model from a supergravity model with a naturally small cosmological constant
Journal of High Energy Physics, 2021 Guided by the naturalness criterion for an exponentially small cosmological constant, we present a string theory motivated 4-dimensional N $$ \mathcal{N} $$ = 1 non-linear supergravity model (or its linear version with a nilpotent superfield) with ...

The Higgs boson mass as fundamental parameter of the minimal supersymmetric standard model
European Physical Journal C: Particles and Fields, 2022 In the Minimal Supersymmetric Standard Model (MSSM) the mass of the lightest neutral Higgs boson is determined by the supersymmetric parameters. In the $$m_h$$ m h MSSM the precisely measured Higgs boson replaces the trilinear coupling $$A_t$$ A t as ...

A Concise Review on Some Higgs-Related New Physics Models in Light of Current Experiments
Universe, 2023 The Higgs boson may serve as a portal to new physics beyond the standard model (BSM), which is implied by the theoretical naturalness or experimental anomalies. This review aims to briefly survey some typical Higgs-related BSM models.

A description of the Galactic Center excess in the Minimal Supersymmetric Standard Model [PDF]
, 2015 Observations with the Fermi Large Area Telescope (LAT) indicate an excess in gamma rays originating from the center of our Galaxy. A possible explanation for this excess is the annihilation of Dark Matter particles.

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 ...

Non-standard charged Higgs decay at the LHC in Next-to-Minimal Supersymmetric Standard Model [PDF]
, 2015 A bstractWe consider next-to-minimal supersymmetric standard model (NMSSM) which has a gauge singlet superfield. In the scale invariant superpotential we do not have the mass terms and the whole Lagrangian has an additional Z3 symmetry.
