Search for electroweak production of charginos in final states with two τ leptons in pp collisions at s = 8 $$ \sqrt{s}=8 $$ TeV [PDF]

open access: diamondJournal of High Energy Physics, 2017
Results are presented from a search for the electroweak production of supersymmetric particles in pp collisions in final states with two τ leptons. The data sample corresponds to an integrated luminosity between 18.1 fb−1 and 19.6 fb−1 depending on the ...

Study of Chargino-Nutralino Pair Production like Higgsinos and Gauginos at The LHC with Three Leptons Final State and Missing Transverse Momentum [PDF]

open access: diamondJournal of Scientific Research in Science, 2022
The calculation of chargino-nutralino pair production at the LHC with √s = 14 TeV had been studied. Different benchmark points are evaluated for the chargino-nutralino pair production using MSSM for four conditions on mass parameters.

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

open access: diamondJournal 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

Combined collider constraints on neutralinos and charginos [PDF]

open access: diamondEuropean Physical Journal C: Particles and Fields, 2019
Searches for supersymmetric electroweakinos have entered a crucial phase, as the integrated luminosity of the Large Hadron Collider is now high enough to compensate for their weak production cross-sections.

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

open access: diamondEuropean 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.

Search for direct production of charginos and neutralinos in events with three leptons and missing transverse momentum in 21 fb−1 of pp collisions at √(s) = 8 TeV with the ATLAS detector [PDF]

open access: diamondEPJ Web of Conferences, 2013
A search for direct chargino and neutralino production processes is presented in a final state with exactly 3 leptons (electrons or muons). No excess over the Standard Model has been observed. The analysis presented is based on 20.7 fb−1 of proton-proton

Search for long-lived charginos based on a disappearing-track signature using 136 fb $$^{-1}$$ - 1 of pp collisions at $$\sqrt{s}$$ s  = 13 TeV with the ATLAS detector

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
A search for long-lived charginos produced either directly or in the cascade decay of heavy prompt gluino states is presented. The search is based on proton–proton collision data collected at a centre-of-mass energy of $$\sqrt{s}$$ s  = 13 T $$\text {eV}$

Explaining muon $${g}-2$$ g - 2 data in the $$\mu \nu $$ μ ν SSM

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
We analyze the anomalous magnetic moment of the muon $$g-2$$ g - 2 in the $$\mu \nu $$ μ ν SSM. This R-parity violating model solves the $$\mu $$ μ problem reproducing simultaneously neutrino data, only with the addition of right-handed neutrinos. In the
