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.

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

open access: yesThe European Physical Journal C, 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 scalar and pseudoscalar Higgs bosons may be separated for $\tan <8$.

Chargino production at the ILC

open access: yes, 2020
The lighter chargino, $\widetilde _1^{\pm}$, is a prime candidate to be the next-to-lightest SUSY particle (the NLSP). Several analyses of $\widetilde _1^{\pm}$ 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.

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

Searches for pair production of charginos and top squarks in final states with two oppositely charged leptons in proton-proton collisions at s = 13 $$ \sqrt{s}=13 $$ TeV

open access: yesJournal of High Energy Physics, 2018
A search for pair production of supersymmetric particles in events with two oppositely charged leptons (electrons or muons) and missing transverse momentum is reported. The data sample corresponds to an integrated luminosity of 35.9 fb−1 of proton-proton
