Search for Pair Production of Supersymmetric Top Quarks Mimicking Standard Model Top Event Signatures at CDF [PDF]

open access: yes, 2008
We present results of the search for the super-symmetric partner of the top quark, the stop quark, decaying to a b-quark and chargino with the subsequent chargino decay into a neutralino, lepton and neutrino.

Constraints on Supersymmetric Models from the Muon Anomalous Magnetic Moment [PDF]

open access: yes, 1996
We study the impact of present and future $(g-2)_\mu$ measurements on supersymmetric models. The corrections to $(g-2)_\mu$ become particularly relevant in the presence of light sleptons, charginos and neutralinos, especially in the large $\tan\beta ...

Polarization of top and chargino from stop decay in natural SUSY

open access: yesPhysics Letters B, 2019
Top squark (stop) plays a crucial role in the naturalness of supersymmetry (SUSY) models, which has been extensively searched for in the LHC experiments.

Search for light scalar top-quark pair production in final states with two leptons with the ATLAS detector in $\sqrt{s}=7\ \mathrm{TeV}$ proton–proton collisions

open access: yesEuropean Physical Journal C: Particles and Fields, 2012
A search is presented for the pair production of light scalar top quarks in $\sqrt{s}=7~\mathrm{TeV}$ proton–proton collisions recorded with the ATLAS detector at the Large Hadron Collider.

MSSM Higgs sector CP violation at photon colliders: Revisited

open access: yes, 2002
We present a comprehensive analysis on the MSSM Higgs sector CP violation at photon colliders including the chargino contributions as well as the contributions of other charged particles.

Chargino decays in the complex MSSM: a full one-loop analysis [PDF]

open access: yes, 2011
We evaluate two-body decay modes of charginos in the Minimal Supersymmetric Standard Model with complex parameters (cMSSM). Assuming heavy scalar quarks we take into account all decay channels involving charginos, neutralinos, (scalar) leptons, Higgs ...

Searches for electroweak production of supersymmetric gauginos and sleptons with the ATLAS detector

open access: yesEPJ Web of Conferences, 2016
This paper shows the summary of the results from some recent research by ATLAS SUSY electroweak group(EWK). The sub-topics are including direct stau production, same-sign chargino pair production via vector boson fusion(VBF) and compressed spectra in ...

Discovery reach for wino and higgsino dark matter with a disappearing track signature at a 100 TeV pp collider

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
Within the theory of supersymmetry, the lightest neutralino is a dark matter candidate and is often assumed to be the lightest supersymmetric particle (LSP) as well.

Light Chargino Effects onto H -> gamma gamma in the MSSM [PDF]

open access: yes, 2013
We analyse the implications of light charginos on the Higgs boson signal strength via gluon-gluon fusion and di-photon decay in the Minimal Supersymmetric Standard Model (MSSM) at the Large Hadron Collider (LHC).

Probing compressed mass spectra in electroweak supersymmetry with Recursive Jigsaw Reconstruction

open access: yesJournal of High Energy Physics, 2018
The lack of evidence for the production of colored supersymmetric particles at the LHC has increased interest in searches for superpartners of the electroweak SM gauge bosons, namely the neutralinos and charginos.
