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}$

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.

Chargino mass and Rb anomaly [PDF]

open access: yesNuclear Physics B, 1996
We re-examine the possible magnitude of the supersymmetric contribution to $R_b$ with imposed all available phenomenological constraints and demanding good quality of the global fit to the precision electroweak data. For low $\tan $ we find a new region of the parameter space, with $M_2\approx | |$ and $ <0$ where $R_b$ remains large, $\sim0.2180$

Chargino contributions to ε and ε′ [PDF]

open access: yesPhysics Letters B, 2001
We analyze the chargino contributions to the K-\bar K mixing and epsilon-prime in the mass insertion approximation and derive the corresponding bounds on the mass insertion parameters. We find that the chargino contributions can significantly enlarge the regions of the parameter space where CP violation can be fully supersymmetric.

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

THE NEUTRALINO MASS: CORRELATION WITH THE CHARGINOS [PDF]

open access: yesModern Physics Letters A, 2006
As the fundamental SU(2) supersymmetric parameters can be determined in the chargino sector, and the remaining fundamental parameters of the minimal supersymmetric extensions of the standard model can be analyzed in the neutralino sector, the two sectors can be correlated via these parameters.

Search for chargino-neutralino production in events with Higgs and W bosons using 137 fb −1 of proton-proton collisions at s $$ \sqrt{s} $$ = 13 TeV

open access: yesJournal of High Energy Physics, 2021
A search for electroweak production of supersymmetric (SUSY) particles in final states with one lepton, a Higgs boson decaying to a pair of bottom quarks, and large missing transverse momentum is presented.
