Abelian Hidden Sectors at a GeV [PDF]

, 2009
We discuss mechanisms for naturally generating GeV-scale hidden sectors in the context of weak-scale supersymmetry. Such low mass scales can arise when hidden sectors are more weakly coupled to supersymmetry breaking than the visible sector, as happens ...

Testing electroweak SUSY for muon g − 2 and dark matter at the LHC and beyond

Journal of High Energy Physics, 2019
Given that the LHC experiment has produced strong constraints on the colored supersymmetric particles (sparticles), testing the electroweak supersymmetry (EWSUSY) will be the next crucial task at the LHC.

Muon g − 2 vs LHC Run 2 in supersymmetric models

Journal of High Energy Physics, 2020
Supersymmetric models with sub-TeV charginos and sleptons have been a candidate for the origin of the long-standing discrepancy in the muon anomalous magnetic moment (g − 2). By gathering all the available LHC Run 2 results, we investigate the latest LHC

A phenomenological study of 5d supersymmetry [PDF]

Journal of High Energy Physics, 2010
Supersymmetry and extra dimension need not be mutually exclusive options of physics for the TeV scale and beyond. In this paper, we envisage a phenomenological scenario by embedding the 4d constrained minimal supersymmetric standard model in a flat 5d $S_1 /Z_2$ orbifold, with the inverse radius of compactification at the TeV scale.

Dark Dimension With (Little) Strings Attached

Fortschritte der Physik, Volume 73, Issue 4, April 2025.
Abstract A relation between dark energy and the scale of new physics in weakly coupled string theory is motivated. This mixing between infrared and ultraviolet physics leads to a unique corner for real‐world phenomenology: barring fine‐tunings, the authors are naturally led to the “dark dimension” scenario, a single mesoscopic extra dimension of micron

Precise prediction of the MSSM Higgs boson masses for low M A

Journal of High Energy Physics, 2018
Precise predictions for Higgs boson masses in the Minimal Supersymmetric Standard Model can be obtained by combining fixed-order calculations with effective field theory (EFT) methods for the resummation of large logarithms in case of heavy super ...

Singlino-dominated dark matter in general NMSSM

Journal of High Energy Physics, 2021
The general Next-to-Minimal Supersymmetric Standard Model (NMSSM) describes the singlino-dominated dark-matter (DM) property by four independent parameters: singlet-doublet Higgs coupling coefficient λ, Higgsino mass μ tot, DM mass m χ ˜ 1 0 $$ {m}_ ...

Phenomenology of supersymmetry with scalar sequestering [PDF]

Physical Review D, 2009
The defining feature of scalar sequestering is that the minimal supersymmetric standard model squark and slepton masses as well as all entries of the scalar Higgs mass matrix vanish at some high scale. This ultraviolet boundary condition--scalar masses vanish while gaugino and Higgsino masses are unsuppressed--is independent of the supersymmetry ...

Foundations of Ghost Stability

Fortschritte der Physik, Volume 73, Issue 4, April 2025.
Abstract The authors present a new method to analytically prove global stability in ghost‐ridden dynamical systems. The proposal encompasses all prior results and consequentially extends them. In particular, it is shown that stability can follow from a conserved quantity that is unbounded from below, contrary to expectation.

CP violating mode of the stoponium decay into Zh

Journal of High Energy Physics, 2018
We show that a novel decay mode Zh of the bound state of stop-anti-stop pair in the ground state 1S0t˜1t˜1* $$ {}^1{S}_0\left({\tilde{t}}_1{\tilde{t}}_1^{*}\right) $$ may have a significant branching ratio if the CP violating mixing appears in the stop ...
