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.

What is the discrete gauge symmetry of the minimal supersymmetric standard model [PDF]

, 2005
We systematically study the extension of the supersymmetric standard model (SSM) by an anomaly-free discrete gauge symmetry Z{sub N}. We extend the work of Ibanez and Ross with N=2, 3 to arbitrary values of N.

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.

Two loop effective potential for the minimal supersymmetric standard model [PDF]

, 2002
I compute the complete two-loop effective potential for the minimal supersymmetric standard model in the Landau gauge. This enables an accurate determination of the minimization conditions for the vacuum expectation values of the Higgs fields.

de Sitter Excited State in Heterotic E8×E8${\rm E}_8 \times {\rm E}_8$ Theory

Fortschritte der Physik, EarlyView.
Abstract A novel duality sequence is devised to study late‐time cosmology in the heterotic E8×E8${\rm E}_8 \times {\rm E}_8$ setup of Horava and Witten with dynamical walls that are moving towards each other. Remarkably, the dimensionally reduced 4‐dimensional theory does not violate NEC and no bouncing or ekpyrotic phase is observed.

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

TOP-INDUCED ELECTROWEAK BREAKING IN THE MINIMAL SUPERSYMMETRIC STANDARD MODEL [PDF]

, 1995
Severe constraints on parameters of the minimal supersymmetric standard model follow from a dynamical electroweak symmetry breaking mechanism dominated by top and stop loops. In particular, the lightest Higgs boson mass is expected to be smaller than 100

Cuprate Twistronics for Quantum Hardware

Advanced Quantum Technologies, EarlyView.
This review bridges decades of foundational research with emerging fabrication techniques such as molecular beam epitaxy and cryogenic stacking. By enabling control over electronic correlations and symmetry in twisted cuprate heterostructures, it highlights how cuprate twistronics could open new paths to overcome decoherence and scalability challenges ...

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 ...

Boundary conditions and universal finite‐size scaling for the hierarchical |φ|4$|\varphi |^4$ model in dimensions 4 and higher

Communications on Pure and Applied Mathematics, Volume 78, Issue 10, Page 2001-2118, October 2025.
Abstract We analyse and clarify the finite‐size scaling of the weakly‐coupled hierarchical n$n$‐component |φ|4$|\varphi |^4$ model for all integers n≥1$n \ge 1$ in all dimensions d≥4$d\ge 4$, for both free and periodic boundary conditions. For d>4$d>4$, we prove that for a volume of size Rd$R^{d}$ with periodic boundary conditions the infinite‐volume ...
