Upper bound of the lightest Higgs boson mass in the minimal supersymmetric standard model
, 1991 In the minimal supersymmetric standard madel, it is shown that a radiative correction of the top and stop loops gives a finite, but non-negligible contribution to Higgs scalar masses if m, "'" 150-250 GeV.

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 ...

Study of diphoton decays of the lightest scalar Higgs boson in the Next-to-Minimal Supersymmetric Standard Model [PDF]
, 2013 The CMS and ATLAS experiments at the LHC have announced the discovery of a Higgs boson with mass at approximately 125 GeV/c2 in the search for the Standard Model Higgs boson via, notably, the γγ and ZZ to four leptons final states. Considering the recent

The Hunting of the MR Model [PDF]
, 1993 We consider experimental signatures of the standard model's minimal supersymmetric extension with a continuous $U(1)_R$ symmetry (MR model). We focus on the ability of existing and planned electron-positron colliders to probe this model and to ...

Lepton Flavor Violation beyond the MSSM
Advances in High Energy Physics, 2015 Most extensions of the Standard Model lepton sector predict large lepton flavor violating rates. Given the promising experimental perspectives for lepton flavor violation in the next few years, this generic expectation might offer a powerful indirect ...

Vacuum stability of the effective Higgs potential in the Minimal Supersymmetric Standard Model
, 2014 The parameters of the Higgs potential of the Minimal Supersymmetric Standard Model (MSSM) receive large radiative corrections which lift the mass of the lightest Higgs boson to the measured value of 126 GeV.

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

Light neutralino dark matter in the next-to-minimal supersymmetric standard model [PDF]
, 2005 Neutralino dark matter is generally assumed to be relatively heavy, with a mass near the electroweak scale. This does not necessarily need to be the case, however.
