Resonant heavy Higgs searches at the HL-LHC

Journal of High Energy Physics, 2019
In this work, we show the importance of searches for heavy resonant scalars (H) and pseudoscalars (A). Taking cue from the present searches, we make projections for searches in an extended scalar sector at the high luminosity run of the Large Hadron ...

Fixed points in supersymmetric extensions of the standard model

European Physical Journal C: Particles and Fields, 2022
We search for weakly interacting fixed points in extensions of the minimally supersymmetric standard model (MSSM). Necessary conditions lead to three distinct classes of anomaly-free extensions involving either new quark singlets, new quark doublets, or ...

Fluxed minimal supersymmetric standard model [PDF]

Physical Review D, 2005
Recent developments in string compactifications in the presence of antisymmetric field backgrounds suggest a new simple and predictive structure for soft terms in the MSSM depending only on two parameters. They give rise to a positive definite scalar potential, a solution to the $\ensuremath{\mu}$-problem, flavor universality and absence of a SUSY-CP ...

The minimally tuned minimal supersymmetric standard model [PDF]

Journal of High Energy Physics, 2008
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 and fine-tuning is minimized with respect to all the important parameters which affect electroweak ...

Supersymmetric D-term Twin Higgs

Journal of High Energy Physics, 2017
We propose a new type of supersymmetric Twin Higgs model where the SU(4) invariant quartic term is provided by a D-term potential of a new U(1) gauge symmetry.

A Relation on Gaugino Masses in a Supersymmetric SO(10)_GUT x SO(6)_H Unified Model

, 1999
The doublet-triplet splitting problem in supersymmetric grand unified theories is elegantly solved in a supersymmetric SO(10)_GUT x SO(6)_H model. In this model, the gauginos in the supersymmetric standard model do not respect the usual GUT gaugino mass ...

Muon (g − 2) in the B-LSSM

Journal of High Energy Physics, 2021
The difference between the updated experimental result on the muon anomalous magnetic dipole moment and the corresponding theoretical prediction of the standard model on that is about 4.2 standard deviations. In this work, we calculate the muon anomalous

Radiative neutralino production in low energy supersymmetric Models. II. The case of beam polarization

, 2012
We study the production of the lightest neutralinos in the radiative process $e^+e^- \to \tilde\chi^0_1 \tilde\chi^0_1\gamma$ in low energy supersymmetric models for the International Linear Collider energies with longitudinally polarized electron and ...

THE MINIMAL SUPERSYMMETRIC STANDARD MODEL [PDF]

Modern Physics Letters A, 1996
The structure of the MSSM is reviewed. We first motivate the particle content of the theory by examining the quantum numbers of the known standard model particles and by the requirement of anomaly cancellation. Once the particle content is fixed we can write down the most general renormalizable superpotential.
