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 ...

Precise estimate of charged Higgsino/Wino decay rate

open access: yesJournal of High Energy Physics
Higgsinos and Winos in the supersymmetric Standard Model are prime candidates for dark matter due to their weakly interacting nature. The mass differences between their charged components (charginos) and neutral components (neutralinos) become degenerate

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.

Search for electroweak production of charginos and sleptons decaying into final states with two leptons and missing transverse momentum in $$\sqrt{s}=13$$ s=13  $$\text {TeV}$$ TeV pp collisions using the ATLAS detector

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
A search for the electroweak production of charginos and sleptons decaying into final states with two electrons or muons is presented. The analysis is based on 139 fb$$^{-1}$$ -1 of proton–proton collisions recorded by the ATLAS detector at the Large ...

Searches for charginos and neutralinos in ATLAS [PDF]

open access: yesProceedings of 7th Annual Conference on Large Hadron Collider Physics — PoS(LHCP2019), 2019
Supersymmetry (SUSY) is one of the most interesting theories describing physics beyond the Standard Model. An extensive program of SUSY searches has been consequently performed by the ATLAS experiment with the LHC data collected during Run-2. In this work, the latest ATLAS searches for charginos and neutralinos are reported.

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.

Chargino production at LEP 200

open access: yesZeitschrift f�r Physik C Particles and Fields, 1992
We study chargino production and decay in the energy region of LEP 200, exploring the relevant supersymmetry parameter space. We give numerical predictions for the cross sections and for the signaturesl++l−+p′, l+jet+p′, jet+jet+p′. New formulae are presented relating chargino masses and couplings to the supersymmetry parameters.
