Singlet scalar top partners from accidental supersymmetry

open access: yesJournal of High Energy Physics, 2018
We present a model wherein the Higgs mass is protected from the quadratic one-loop top quark corrections by scalar particles that are complete singlets under the Standard Model (SM) gauge group.

High-Precision Calculations of the Higgs Boson Mass

open access: yesParticles, 2022
In this paper, we review the status of the computations of the perturbative quantum corrections to the Higgs boson mass in the Standard Model and in its supersymmetric extensions. In particular, supersymmetric theories require a very accurate computation

b -> s gamma in the left-right supersymmetric model

open access: yes, 2002
The rare decay $b \to s \gamma$ is studied in the left-right supersymmetric model. We give explicit expressions for all the amplitudes associated with the supersymmetric contributions coming from gluinos, charginos and neutralinos in the model to one ...

Bounds on Supersymmetry from Electroweak Precision Analysis [PDF]

open access: yes, 1998
The Standard Model global fit to precision data is excellent. The Minimal Supersymmetric Standard Model can also fit the data well, though not as well as the Standard Model.

Gluino-SUGRA scenarios in light of FNAL muon g – 2 anomaly

open access: yesJournal of High Energy Physics, 2021
Gluino-SUGRA ( g ~ $$ \overset{\sim }{g} $$ SUGRA), which is an economical extension of the predictive mSUGRA, adopts much heavier gluino mass parameter than other gauginos mass parameters and universal scalar mass parameter at the unification scale.

INFLATION AND THE MINIMAL SUPERSYMMETRIC STANDARD MODEL [PDF]

open access: yesModern Physics Letters A, 2008
There is strong evidence from cosmological data that the universe underwent an epoch of superluminal expansion called inflation. A satisfactory embedding of inflation in fundamental physics has been an outstanding problem at the interface of cosmology and high energy physics.

Supersymmetric hidden sectors for heterotic standard models [PDF]

open access: yesJournal of High Energy Physics, 2013
Within the context of the weakly coupled E8 x E8 heterotic string, we study the hidden sector of heterotic standard model compactifications to four-dimensions. Specifically, we present a class of hidden sector vector bundles - composed of the direct sum of line bundles only - that, together with an effective bulk five-brane, renders the heterotic ...

Non-Supersymmetric Extensions of the Standard Model [PDF]

open access: yes, 1996
The motivations for studying dynamical scenarios of electroweak and flavor symmetry breaking are reviewed and the latest ideas, especially topcolor-assisted technicolor, are summarized.

Supersymmetric Higgs Singlet Effects on B-Meson FCNC Observables at Large tan(beta) [PDF]

open access: yes, 2008
Higgs singlet superfields are usually present in most extensions of the Minimal Supersymmetric Standard Model (MSSM) that address the mu-problem, such as the Next-to-Minimal Supersymmetric Standard Model (NMSSM) and the Minimal Nonminimal Supersymmetric ...

CP violation in minimal supersymmetric standard model [PDF]

open access: yesNuclear Physics B - Proceedings Supplements, 1994
$CP$ violating phenomena predicted by the minimal supersymmetric standard model are discussed in a case where the $CP$ violating phases in SUSY sector are not suppressed. The electric dipole moments of the neutron and the electron are large, but can be smaller than their experimental upper bounds if the scalar quarks and leptons are heavier than a few ...
