R-parity violating decays of Wino chargino and wino neutralino LSPs and NLSPs at the LHC [PDF]

open access: yesJournal of High Energy Physics, 2019
The R-parity violating decays of both Wino chargino and Wino neutralino LSPs are analyzed within the context of the B − L MSSM “heterotic standard model”.

Constraining slepton and chargino through compressed top squark search [PDF]

open access: yesJournal of High Energy Physics, 2018
We examine the compressed mass spectrum with sub-TeV top squark t˜ $$ \left(\tilde{t}\right) $$ as lightest colored (s)particle in natural supersymmetry (SUSY). Such spectra are searched along with an additional hard jet, not only to boost the soft decay

Chargino and neutralino production at $$e^+e^-$$ e + e - colliders in the complex MSSM: a full one-loop analysis [PDF]

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
For the search for charginos and neutralinos in the Minimal Supersymmetric Standard Model (MSSM) as well as for future precision analyses of these particles an accurate knowledge of their production and decay properties is mandatory.

Chargino contributions in light of recent ϵ′/ϵ [PDF]

open access: yesPhysics Letters B, 2016
Recently, the standard model prediction of ϵ′/ϵ was improved, and a discrepancy from the experimental results was reported at the 2.9σ level. We study the chargino contributions to Z penguin especially with the vacuum stability constraint.

Prospects for chargino pair production at CEPC [PDF]

open access: yesChinese Physics C, High Energy Physics & Nuclear Physics, 2021
The proposed Circular Electron Positron Collider (CEPC), with a center-of-mass energy √ s = 240 GeV, will primarily serve as a Higgs factory. At the same time, it can offer good opportunities to search for new physics phenomena at low energy, which can ...

Search for chargino--neutralino pair production in final states with three leptons and missing transverse momentum in $\sqrt{s} = 13$ TeV $pp$ collisions with the ATLAS detector [PDF]

open access: yes, 2021
A search for chargino$-$neutralino pair production in three-lepton final states with missing transverse momentum is presented. The study is based on a dataset of $\sqrt{s} = 13$ TeV $pp$ collisions recorded with the ATLAS detector at the LHC ...

Search for trilepton resonances from chargino and neutralino pair production in $\sqrt{s}$ = 13 TeV $pp$ collisions with the ATLAS detector [PDF]

open access: yes, 2020
A search is performed for the electroweak pair production of charginos and associated production of a chargino and neutralino, each of which decays through an $R$-parity-violating coupling into a lepton and a $W$, $Z$, or Higgs boson.

Neutralino-chargino pair production at NLO+NLL with resummation-improved parton density functions for LHC Run II [PDF]

open access: yesPhysical Review D, 2018
We make use of recently released parton density functions (PDFs) with threshold-resummation improvement to consistently calculate theoretical predictions for neutralino and chargino pair production at next-to-leading order and next-to-leading logarithmic

Search for chargino-neutralino production using recursive jigsaw reconstruction in final states with two or three charged leptons in proton-proton collisions at $\sqrt{s}$=13 TeV with the ATLAS detector [PDF]

open access: yes, 2018
A search for electroweak production of supersymmetric particles is performed in two-lepton and three-lepton final states using recursive jigsaw reconstruction. The search uses data collected in 2015 and 2016 by the ATLAS experiment in $\sqrt{s}$ = 13 TeV

Constraining the R -symmetric chargino NLSP at the LHC [PDF]

open access: yesPhysical Review D, 2018
We present a phenomenological study of Dirac electroweakinos in a $U(1)_R$ extension of the MSSM with a strictly $R$-symmetric Higgs sector (MRSSM) and gauge-mediated supersymmetry breaking.
