Supersymmetric preons and the standard model

Nuclear Physics B, 2018
The experimental fact that standard model superpartners have not been observed compels one to consider an alternative implementation for supersymmetry.

Leptonic CP Violation in Supersymmetric Standard Model [PDF]

Physical Review D, 1994
We point out the possibility of spontaneous and hard CP-violation in the scalar potential of R-parity broken supersymmetric Standard Model. The existence of spontaneous CP-violation depends crucially on the R-parity breaking terms in the superpotential ...

Linking the supersymmetric standard model to the cosmological constant [PDF]

Journal of High Energy Physics, 2021
String theory has no parameter except the string scale M S , so the Planck scale M Pl, the supersymmetry-breaking scale , the electroweak scale m EW as well as the vacuum energy density (cosmological constant) Λ are to be determined dynamically at any ...

Proposal for a Supersymmetric Standard Model [PDF]

Physical Review Letters, 2005
The fact that neutrinos are massive suggests that the minimal supersymmetric standard model (MSSM) might be extended in order to include three gauge-singlet neutrino superfields with Yukawa couplings of the type $H_2 L \nu^c$.

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

The Minimally Tuned Minimal Supersymmetric Standard Model [PDF]

Journal of High Energy Physics, 2007
The regions in the Minimal Supersymmetric Standard Model with the minimal amount of fine-tuning of electroweak symmetry breaking are presented for general messenger scale. No a priori relations among the soft supersymmetry breaking parameters are assumed

A 125 GeV Higgs and Its Diphoton Signal in Different SUSY Models: A Mini Review [PDF]

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 (

Phenomenology of the utilitarian supersymmetric standard model

Nuclear Physics B, 2016
We study the 2010 specific version of the 2002 proposed U(1)X extension of the supersymmetric standard model, which has no μ term and conserves baryon number and lepton number separately and automatically.
