Search for chargino-neutralino production with mass splittings near the electroweak scale in three-lepton final states in √s = 13 TeV pp collisions with the ATLAS detector [PDF]

open access: yes, 2019
A search for supersymmetry through the pair production of electroweakinos with mass splittings near the electroweak scale and decaying via on-shell W and Z bosons is presented for a three-lepton fi ...

Confronting the neutralino and chargino sector of the NMSSM with the multilepton searches at the LHC [PDF]

open access: yesPhysical Review D, 2018
We test the impact of the ATLAS and CMS multi-lepton searches performed at the LHC with 8 as well as 13 TeV center-of-mass energy (using only the pre-2018 results) on the chargino and neutralino sector of the NMSSM.

Supergravity Model of Inflation and Explaining IceCube HESE Data via PeV Dark Matter Decay

open access: yesAdvances in High Energy Physics, Volume 2020, Issue 1, 2020., 2020
We construct a unified model of inflation and PeV dark matter with an appropriate choice of no‐scale Kähler potential, superpotential, and gauge kinetic function in terms of MSSM fields and hidden sector Polonyi field. The model is consistent with the CMB observations and can explain the PeV neutrino flux observed at IceCube HESE.

Search for chargino and neutralino production in final states with a Higgs boson and missing transverse momentum at √s=13 TeV with the ATLAS detector [PDF]

open access: yes, 2018
A search is conducted for the electroweak pair production of a chargino and a neutralino pp -> (chi) over tilde (+/-)(1)(chi) over tilde (0)(2), where the chargino decays into the lightest neutr ...

Search for top squarks decaying via four-body or chargino-mediated modes in single-lepton final states in proton-proton collisions at $\sqrt{s} =$ 13 TeV [PDF]

open access: yes, 2018
A search for the pair production of the lightest supersymmetric partner of the top quark (̃t1) is presented. The search focuses on a compressed scenario where the mass difference between the top squark and the lightest supersymmetric particle, often ...

Searches for electroweak neutralino and chargino production in channels with Higgs, Z, and W bosons in pp collisions at 8 TeV Searches for Electroweak Neutralino [PDF]

open access: yes, 2014
Searches for supersymmetry (SUSY) are presented based on the electroweak pair production of neutralinos and charginos, leading to decay channels with Higgs, Z, and W bosons and undetected lightest SUSY particles (LSPs).

Chargino Production at an e-e- Collider [PDF]

open access: yes, 1997
The chargino pair production in $e^-e^-$ collisions with their subsequent decays are considered within SUSY models with R-parity violation and with lepton number non-conservation.

Search for electroweak production of charginos in final states with two τ leptons in pp collisions at s = 8 $$ \sqrt{s}=8 $$ TeV

open access: yesJournal of High Energy Physics, 2017
Results are presented from a search for the electroweak production of supersymmetric particles in pp collisions in final states with two τ leptons. The data sample corresponds to an integrated luminosity between 18.1 fb−1 and 19.6 fb−1 depending on the ...

Muon g − 2 vs LHC Run 2 in supersymmetric models

open access: yesJournal of High Energy Physics, 2020
Supersymmetric models with sub-TeV charginos and sleptons have been a candidate for the origin of the long-standing discrepancy in the muon anomalous magnetic moment (g − 2). By gathering all the available LHC Run 2 results, we investigate the latest LHC
