Upper bounds on sparticle masses from muon g-2 and the Higgs mass and the complementarity of future colliders

open access: yes, 2015
Supersymmetric (SUSY) explanation of the discrepancy between the measurement of $(g-2)_\mu$ and its SM prediction puts strong upper bounds on the chargino and smuon masses.

Search for electroweak production of charginos and sleptons decaying into final states with two leptons and missing transverse momentum in $$\sqrt{s}=13$$ s=13  $$\text {TeV}$$ TeV pp collisions using the ATLAS detector

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
A search for the electroweak production of charginos and sleptons decaying into final states with two electrons or muons is presented. The analysis is based on 139 fb$$^{-1}$$ -1 of proton–proton collisions recorded by the ATLAS detector at the Large ...

Precision measurements of Higgs-chargino couplings in chargino pair production at a muon collider [PDF]

open access: yes, 2003
We study chargino pair production on the heavy Higgs resonances at a muon collider in the MSSM. At $\sqrt{s} \approx 350$ GeV cross sections up to 2 pb are reached depending on the supersymmetric scenario and the beam energy spread. The resonances of the

Precise estimate of charged Higgsino/Wino decay rate

open access: yesJournal of High Energy Physics
Higgsinos and Winos in the supersymmetric Standard Model are prime candidates for dark matter due to their weakly interacting nature. The mass differences between their charged components (charginos) and neutral components (neutralinos) become degenerate

Higgs, di-Higgs and tri-Higgs production via SUSY processes at the LHC with 14 TeV [PDF]

open access: yes, 2015
We have systematically investigated the production of a Higgs boson with a mass of about $125$ GeV in the decays of supersymmetric particles within the phenomenological MSSM (pMSSM).

Search for disappearing tracks as a signature of new long-lived particles in proton-proton collisions at s=13 $$ \sqrt{s}=13 $$ TeV

open access: yesJournal of High Energy Physics, 2018
A search is presented for long-lived charged particles that decay within the CMS detector and produce the signature of a disappearing track. A disappearing track is an isolated track with missing hits in the outer layers of the silicon tracker, little or

Search for direct chargino production in anomaly-mediated supersymmetry breaking models based on a disappearing-track signature in pp collisions at $ \sqrt{s}=7\;\mathrm{TeV} $ with the ATLAS detector

open access: yes, 2013
A bstractA search for direct chargino production in anomaly-mediated supersymmetry breaking scenarios is performed in pp collisions at $ \sqrt{s}=7\;\mathrm{TeV} $ using 4.7 fb−1 of data collected with the ATLAS experiment at the LHC.

Muon $$\mathbf {g-2}$$ g - 2 , neutralino dark matter and stau NLSP

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
We explore the implications of resolving the muon $$g-2$$ g - 2 anomaly in a $$SU(4)_c \times SU(2)_L \times SU(2)_R$$ S U ( 4 ) c × S U ( 2 ) L × S U ( 2 ) R model, where the soft supersymmetry breaking scalar and gaugino masses break the left-right (LR)

Dark Matter Constraints on Gaugino/Higgsino Masses in Split Supersymmetry and Their Implications at Colliders

open access: yes, 2005
In split supersymmetry, gauginos and Higgsinos are the only supersymmetric particles which are possibly accessible at foreseeable colliders. While the direct experimental searches, such as LEP and Tevatron experiments, gave robust lower bounds on the ...

The neutralino projector formalism for complex SUSY parameters [PDF]

open access: yes, 2002
We present a new formalism describing the neutralino physics in the context of the minimal supersymmetric model (MSSM), where CP violation induced by complex $M_1$ and $\mu$ parameters is allowed.
