Chargino production at the ILC

  title={Chargino production at the ILC},
  author={Mar'ia Teresa N'unez Pardo de Vera and Mikael Berggren and Jenny List},
  journal={arXiv: High Energy Physics - Phenomenology},
The lighter chargino, $\widetilde{\chi}_1^{\pm}$, is a prime candidate to be the next-to-lightest SUSY particle (the NLSP). Several analyses of $\widetilde{\chi}_1^{\pm}$ pair-production at the ILC, at specific model-points, have been performed, showing that detection and property-determination is possible, even for very difficult cases. However, no recent studies have evaluated the reach of the ILC to detect $\widetilde{\chi}_1^{\pm}$ pair production in general. In this study, cross sections… 

Investigation of production of neutral Higgs boson and two charged charginos from electron-positron annihilation via different propagators

In the current work we investigated the production of neutral Higgs boson ( H ℓ° ) and two charged Charginos ( χ̃ i+ , χ̃ j− ) owing to electron-positron annihilation via different propagators for

ILC Study Questions for Snowmass 2021

To aid contributions to the Snowmass 2021 US Community Study on physics at the International Linear Collider and other proposed $e^+e^-$ colliders, we present a list of study questions that could be

Dark Matter in Supersymmetry

Supersymmetry is a well-motivated theory for physics beyond the Standard Model. In particular, supersymmetric models can naturally possess dark matter candidates that can give rise to the measured

Creation of Two Charginos and Neutralino Via Different Propagators

We investigated the creation of two Charginos ( (cid:1)(cid:2) ± ) and neutralino ( (cid:1)(cid:2) (cid:4) ) owing to electron-positron annihilation via the process (cid:5) (cid:6) (cid:7)(cid:8)

Improved $$(g-2)_\mu $$ measurements and supersymmetry

The electroweak (EW) sector of the Minimal Supersymmetric Standard Model (MSSM) can account for a variety of experimental data. The lighest supersymmetric particle (LSP), which we take as the

Impact of $e^+$ and $e^-$ beam polarization on chargino and neutralino production at a linear collider

Abstract. We study the production processes $e^+ e^-\to \tilde{\chi}^+_i \tilde{\chi}^-_j$, $i,j=1,2$, and $e^+ e^-\to \tilde{\chi}^0_m \tilde{\chi}^0_n, m,n= 1,\ldots,4$, working out the advantages

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

A bstractThis paper presents a search for direct electroweak gaugino or gluino pair production with a chargino nearly mass-degenerate with a stable neutralino. It is based on an integrated luminosity

Constraining the Sneutrino Mass in Chargino Production and Decay with Polarized Beams

Production and decay of gaugino-like charginos are crucially determined by sneutrino exchange. Therefore we study the pair production of charginos e^+ e^- -> chi^+_1 chi^-_1 with polarized beams and

Combined LHC/ILC analysis of a SUSY scenario with heavy sfermions

We discuss the potential of analyses at the Large Hadron Collider and the planned International Linear Collider to explore low-energy supersymmetry in a difficult region of the parameter space


In this paper, we describe the key features of the recently completed technical design for the International Linear Collider (ILC), a 200–500 GeV linear electron–positron collider (expandable to 1

Phenomenological impacts of the CP odd rephase invariant phase of the chargino mass matrix in the production of light chargino pair in e+ e- collisions

One CP--odd rephase-invariant phase appears in the chargino mass matrix in the minimal Supersymmetric Standard Model. We investigate in detail the phenomenological impacts of the CP-odd complex phase
