Taking aim at the wino-Higgsino plane with the LHC

LM Carpenter, H Gilmer, J Kawamura, T Murphy - Physical Review D, 2024 - APS
In this work we explore multiple search strategies for Higgsinos and mixed Higgsino-wino
states in the minimal supersymmetric Standard Model (MSSM) and project the results onto …

Constraints on nonuniversal gaugino mass scenario using the latest LHC data

J Kawamura, Y Omura - Physical Review D, 2016 - APS
We investigate exclusion limits on the nonuniversal gaugino mass scenario in the minimal
supersymmetric standard model (MSSM), according to the latest results of the superparticle …

Moduli stabilization to a natural MSSM with gravitino dark matter and inflation

H Otsuka - Physical Review D, 2015 - APS
We propose the gravitino dark matter in the gravity mediated supersymmetry breaking
scenario. The mass hierarchies between the gravitino and other superparticles can be …

Probing the hyperbolic branch/focus point region of the constrained minimal supersymmetric standard model with generalized Yukawa quasiunification

N Karagiannakis, G Lazarides, C Pallis - Physical Review D, 2015 - APS
We analyze the parametric space of the constrained minimal supersymmetric standard
model with μ> 0 supplemented by a generalized asymptotic Yukawa coupling …

Peccei-Quinn violating minimal supergravity and a 126 GeV Higgs boson

C Balazs, SK Gupta - Physical Review D—Particles, Fields, Gravitation, and …, 2013 - APS
In a Peccei-Quinn extension of supergravity the h→ γ γ detection rate can be significantly
enhanced due to the reduction of the total Higgs decay width. To assess the viability of …

Precise focus point scenario for a natural Higgs boson in the MSSM

B Kyae, CS Shin - Physical Review D, 2014 - APS
A small Higgs mass parameter mhu 2 can be insensitive to various trial heavy stop masses,
if a universal soft squared mass is assumed for the chiral superpartners and the Higgs …

Inert Higgs doublet extension of the NMSSM

B Kyae - Physical Review D, 2014 - APS
We introduce one pair of inert Higgs doublets {H d, H u} and singlets {N c, N}, and consider
their couplings with the Higgs doublets of the minimal supersymmetric standard model …

Radiative Enhancement of Stop Mixing

KS Jeong - Journal of the Korean Physical Society, 2020 - Springer
A supersymmetric extension of the Standard Model should rely on the mixing in the stop
sector in order to accommodate the 125 GeV Higgs boson if the stops are around or below …
