Radiative corrections to chargino production with polarized beams [PDF]

open access: green, 2001
We show that radiative corrections to chargino production in electron-positron annihilation with polarized beams can be large especially in the case of right handed electrons.

Single chargino production with R-parity lepton number violation in electron-electron and muon-muon collisions

open access: green, 2000
We examine single chargino production in conjunction with R-parity lepton number violation in future lepton-lepton collisions. Present bounds on R-parity violating couplings allow for a production cross section of the order of ${\cal{O}} (10 {fb})$ for a

CPviolation at one loop in the polarization-independent chargino production ine+ecollisions [PDF]

open access: green, 2007
Recently Osland and Vereshagin noticed, based on sample calculations of some box diagrams, that in unpolarised e+e- collisions CP-odd effects in the non-diagonal chargino-pair production process are generated at one-loop.

Measuring the Mass of the Lightest Chargino at the CERN LHC

open access: green, 2003
Results are presented of a feasibility study of techniques for measuring the mass of the lightest chargino at the CERN LHC. These results suggest that for one particular mSUGRA model a statistically significant chargino signal can be identified and the ...

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

open access: yesJournal 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.

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

Search for direct production of electroweakinos in final states with one lepton, jets and missing transverse momentum in pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2023
Searches for electroweak production of wino-like chargino pairs, χ ~ 1 + χ ~ 1 − $$ {\overset{\sim }{\chi}}_1^{+}{\overset{\sim }{\chi}}_1^{-} $$ , and of wino-like chargino and next-to-lightest neutralino, χ ~ 1 ± χ ~ 2 0 $$ {\overset{\sim }{\chi}}_1 ...
