Neutralino warm dark matter [PDF]

open access: yesPhysics Letters B, 2001
In the supersymmetric (SUSY) standard model, the lightest neutralino may be the lightest SUSY particle (LSP), and it is is a candidate of the dark matter in the universe. The LSP dark matter might be produced by the non-thermal process such as heavy particle decay after decoupling of the thermal relic LSP.

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).

SUSY-QCD corrections for direct detection of neutralino dark matter and correlations with relic density [PDF]

open access: yes, 2016
In this paper, we perform a full next-to-leading order (NLO) QCD calculation of neutralino scattering on protons or neutrons in the MSSM. We match the results of the NLO QCD calculation to the scalar and axial-vector operators in the effective field ...

Combined search for electroweak production of charginos and neutralinos in proton-proton collisions at s = 13 $$ \sqrt{s}=13 $$ TeV

open access: yesJournal of High Energy Physics, 2018
A statistical combination of several searches for the electroweak production of charginos and neutralinos is presented. All searches use proton-proton collision data at s = 13 $$ \sqrt{s}=13 $$ TeV, recorded with the CMS detector at the LHC in 2016 and ...

Testing Yukawa unification at LHC Run-3 and HL-LHC

open access: yesJournal of High Energy Physics, 2020
We explore t-b-τ Yukawa unification (YU) in a supersymmetric SU(4) c × SU(2) L × SU(2) R model without imposing a discrete left-right (L-R) symmetry.

Dark Matter Constraints and the Neutralino Sector of the scNMSSM

open access: yesUniverse, 2021
The neutralino sector of the semi-constrained next-to-minimal supersymmetric standard model is explored under recent experimental constraints, with special attention to dark matter (DM) limits.

One-loop renormalisation of the NMSSM in SloopS : 1. the neutralino-chargino and sfermion sectors [PDF]

open access: yes, 2016
We have completed the one-loop renormalisation of the Next-to-Minimal Supersymmetric Standard Model (NMSSM) allowing for and comparing between different renormalisation schemes. A special attention is paid to on-shell schemes. We study a variety of these

Towards the Final Word on Neutralino Dark Matter [PDF]

open access: yes, 2015
We present a complete phenomenological prospectus for thermal relic neutralinos. Including Sommerfeld enhancements to relic abundance and halo annihilation calculations, we obtain direct, indirect, and collider discovery prospects for all neutralinos ...

WIMP/NEUTRALINO DIRECT DETECTION [PDF]

open access: yesInternational Journal of Modern Physics A, 2004
The most popular candidate for non-baryonic dark matter is the neutralino. More than twenty experiments are dedicated to its direct detection. This review describes the most competitive and promising experiments with different detection techniques. The most recent results are presented with some prospects for the near future.
