String Model Building on Quantum Annealers
Fortschritte der Physik, Volume 71, Issue 12, December 2023., 2023 Abstract For the first time the direct construction of string models on quantum annealers has been explored and has been investigated their efficiency and effectiveness in the model discovery process. Through a thorough comparison with traditional methods such as simulated annealing, random scans, and genetic algorithms, it is highlighted the potential

Bumping into the Species Scale with the Scalar Potential
Fortschritte der Physik, Volume 71, Issue 10-11, November 2023., 2023 Abstract As a quantum gravity cut‐off, the species scale Λs$\Lambda _s$ gets naturally compared to the energy scale of a scalar potential V in an EFT. In this note, the species scale, its rate |∇Λs|/Λs$|\nabla \Lambda _s|/\Lambda _s$ and their field dependence, to those of a scalar potential is compared.

A 125 GeV Higgs and Its Diphoton Signal in Different SUSY Models: A Mini Review
Advances in High Energy Physics, 2012 In this paper we briefly review our recent studies on a 125 GeV Higgs and its diphoton signal rate in different low-energy supersymmetric models, namely, the minimal supersymmetric standard model (MSSM), the next-to-minimal supersymmetric standard model (

Higgs Boson Mass Bounds in the Standard and Minimal Supersymmetric Standard Model with Four Generations [PDF]
Mod.Phys.Lett. A12 (1997) 553-560, 1997 We study the question of distinguishability of the Higgs sector between the standard model with four generations(SM4) and the minimal supersymmetric standard model with four generations (MSSM4). We find that a gap exists between the SM4 and MSSM4 Higgs boson masses for a range of the fourth generation fermion mass considered in the analysis at a fixed ...

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.

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 ...

The Minimal Supersymmetric Standard Model (MSSM) with $R$-Parity Violation [PDF]
arXiv, 2022 In this lectures, we give a review about the Minimal Supersymmetric Standard Model (MSSM) with $R$-Parity Violation because it provides an attractive way to generate neutrino masses, lepton mixing angles in acconcordance to present neutrino data.

Collider phenomenology of a gluino continuum
Journal of High Energy Physics, 2020 Continuum supersymmetry is a class of models in which the supersymmetric partners together with part of the standard model come from a conformal sector, broken in the IR near the TeV scale.

Lightest Higgs boson decays h → MZ in the μ from ν supersymmetric standard model
Journal of High Energy Physics, 2023 We study the lightest Higgs boson decays h → MZ in the μ from ν supersymmetric standard model (μνSSM), where M is a vector meson (ρ, ω, ϕ, J/Ψ, Υ). Compared to the minimal supersymmetric standard model (MSSM), the μνSSM introduces three right-handed ...

The manifestly gauge-invariant spectrum of the Minimal Supersymmetric Standard Model [PDF]
arXiv, 2023 Formal field theory requires, even in the presence of a Brout-Englert-Higgs effect, to maintain manifest non-perturbative gauge invariance. The Fr\"ohlich-Morchio-Strocchi mechanism allows nonetheless an augmented perturbative treatment. We perform such an augmented tree-level analysis for the minimal supersymmetric standard model. We find that, as for
