Decays of W bosons to charginos and neutralinos [PDF]

open access: greenPhysics Letters B, 1997
The region of the supersymmetry parameter space, in which charginos decay predominantly into sneutrinos and leptons: chi+ -> \tilde + l+, is not excluded experimentally for small mass differences between charginos and sneutrinos. The decay sneutrinos are invisible in R-parity conserving theories since they are either the lightest supersymmetric ...

Chargino and neutralino decays revisited [PDF]

open access: greenThe European Physical Journal C, 2001
We perform a comprehensive analysis of the decays of charginos and neutralinos in the Minimal Supersymmetric Standard Model where the neutralino $ _1^0$ is assumed to be the lightest supersymmetric particle. We focus, in particular, on the three-body decays of the next-to-lightest neutralino and the lightest chargino into the lightest neutralino and ...

Phenomenology of the chargino and neutralino systems [PDF]

open access: greenAIP Conference Proceedings, 2001
The chargino and neutralino pair production processes at $e^+e^-$ collisions are explored to determine the underlying SUSY parameters. The sum rules for the couplings are used to check the closure of two-chargino and four-neutralino systems in the minimal supersymmetric extension of the standard model.

Search for charginos and neutralinos at LEP [PDF]

open access: greenNuclear Physics B - Proceedings Supplements, 2000
Abstract A summary of the search for charginos and neutralinos at LEP is given, with the latest results from the √s = 189 GeV run. The emphasis will be on models that provide as stable Lightest Supersymmetric Particle, which could turn out to constitute an important part of the dark matter.

Combined collider constraints on neutralinos and charginos [PDF]

open access: yesEuropean 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.

Pair production of the lightest chargino at γγ-collider

open access: yesNuclear Physics B, 2019
Chargino pair production via photon–photon collision is investigated in the Minimal Supersymmetric Standard Model at a future linear collider. The process is computed using all the possible diagrams at the next-to-leading order, including box, triangle ...

SUSY Parameters from Charginos

open access: green, 2002
The chargino pair production processes at $e^+e^-$ collisions are explored to reconstruct the fundamental SUSY parameters: the SU(2) gaugino parameter $M_2$, the higgsino mass parameter $ $ and $\tan $. Both CP-conserving and CP-violating SUSY sectors are discussed.

Prospects for chargino pair production at the CEPC * [PDF]

open access: yesChinese Physics C, 2022
Abstract The proposed Circular Electron Positron Collider (CEPC) with a center-of-mass energy GeV will primarily serve as a Higgs factory. Additionally, it will offer good opportunities to search for new physics phenomena at low energies, which can be challenging with ...
