Bayesian analysis and naturalness of (Next-to-)Minimal Supersymmetric Models
Journal of High Energy Physics, 2017 The Higgs boson discovery stirred interest in next-to-minimal supersymmetric models, due to the apparent fine-tuning required to accommodate it in minimal theories.

Recent results on beyond the standard model Higgs boson searches from CMS
EPJ Web of Conferences, 2012 Two extensions of the standard model, one that includes the seesaw mechanism of type II, and the minimal supersymmetric extention to the standard model, are studied using up to 1.6 fb−1 of data collected in proton-proton collisions at √s = 7 TeV with the

Electroweak phase transition in a right-handed neutrino superfield extended NMSSM
Journal of High Energy Physics, 2023 Supersymmetric models with singlet extensions can accommodate single- or multi-step first-order phase transitions (FOPT) along the various constituent field directions.

Fortschritte der Physik, Volume 74, Issue 4, April 2026.Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

Improved predictions for intermediate and heavy supersymmetry in the MSSM and beyond
European Physical Journal C: Particles and Fields, 2017 For a long time, the minimal supersymmetric standard model (MSSM) with light masses for the supersymmetric states was considered as the most natural extension of the Standard Model of particle physics. Consequently, a valid approximation was to match the

Electric Dipole Moments in the Generic Supersymmetric Standard Model [PDF]
, 2001 The generic supersymmetric standard model is a model built from a supersymmetrized standard model field spectrum the gauge symmetries only. The popular minimal supersymmetric standard model differs from the generic version in having R-parity imposed by ...

Fortschritte der Physik, Volume 74, Issue 1, January 2026.Abstract The propagation of a massive scalar field and a massless Dirac field in the geometry of a dilaton–de Sitter black hole is investigated. Starting from the covariant perturbation equations, the corresponding effective potentials are presented and their dependence on the dilaton charge, field mass, and cosmological constant is analyzed. Using the

Supersymmetry and Beyond Standard Model Higgs searches at ATLAS
EPJ Web of Conferences, 2012 The searches for supersymmetric and beyond Standard Model Higgs boson with the ATLAS detector are presented. The results are based on integrated luminosity of 35 pb−1 to 1.6 fb−1 of proton-proton collision data recorded at a centre-of-mass energy of 7 ...

Bottom quark contribution to spin-dependent dark matter detection
Nuclear Physics B, 2016 We investigate a previously overlooked bottom quark contribution to the spin-dependent cross section for Dark Matter (DM) scattering from the nucleon. While the mechanism is relevant to any supersymmetric extension of the Standard Model, for illustrative
