Least supersymmetric standard model

open access: yesPhysical Review D, 2012
We propose the minimal (least) version of the supersymmetric standard model which can solve the hierarchy problem in the same way as the so-called minimal supersymmetric standard model and presents solutions to some of its problems. Supersymmetry is broken in a secluded sector and mediated to the observable sector by messengers of a gauge group $G ...

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

Neutrino Magnetic Moment in the Doublet‐Singlet Leptoquark Model

open access: yesAdvances in High Energy Physics, Volume 2026, Issue 1, 2026.
The transition magnetic moment for Majorana neutrinos is studied in a simple extension of the Standard Model. This extension incorporates two scalar Leptoquarks S1 and R~2 with quantum numbers 3¯,113,/ and (3, 2, 1/6), respectively. It is found that these Leptoquarks generate a sizable transition magnetic moment, particularly when the quark bottom is ...

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.

A Superalgebra Within: Representations of Lightest Standard Model Particles Form a Z25$\mathbb {Z}_2^5$‐Graded Algebra

open access: yesAnnalen der Physik, Volume 537, Issue 12, December 2025.
 A set of particle representations, familiar from the Standard Model, collectively form a superalgebra. Those representations mirroring the behaviour of the Standard Model's gauge bosons, and three generations of fermions, are each included in this algebra, with exception only to those representations involving the top quark.

Rough Quasi‐Conformal Mapping for Realizing Omnidirectional Light Wave Manipulation in Lower‐Index Meta‐Lens

open access: yesLaser &Photonics Reviews, Volume 19, Issue 24, December 17, 2025.
A rough quasi‐conformal mapping strategy breaks the rigid geometric constraints of transformation optics. By trading perfect local angle preservation for a dramatically reduced refractive index, this design paradigm enables the creation of ultra‐flat, wide‐angle, and even omnidirectional lenses that are both high‐performance and manufacturable, opening

Resonant heavy Higgs searches at the HL-LHC

open access: yesJournal 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 ...

de Sitter Excited State in Heterotic E8×E8${\rm E}_8 \times {\rm E}_8$ Theory

open access: yesFortschritte der Physik, Volume 73, Issue 12, December 2025.
Abstract A novel duality sequence is devised to study late‐time cosmology in the heterotic E8×E8${\rm E}_8 \times {\rm E}_8$ setup of Horava and Witten with dynamical walls that are moving towards each other. Remarkably, the dimensionally reduced 4‐dimensional theory does not violate NEC and no bouncing or ekpyrotic phase is observed.

Supersymmetric D-term Twin Higgs

open access: yesJournal 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.
