Collider signatures of a light NMSSM pseudoscalar in neutralino decays in the light of LHC results [PDF]

open access: yes, 2013
A bstractWe investigate signatures induced by a very light pseudoscalar Higgs in neutralino decays in the Next-to-Minimal Supersymmetric Standard Model (NMSSM) and determine their observability at the LHC.

Gamma radiation by neutralino stars [PDF]

open access: yesPhysics Letters A, 1997
A new model of gamma radiation (GR) generated by neutralino annihilation in neutralino stars (NeS) is proposed. Diffuse Galactic and extragalactic GR is calculated for this model and is shown to be in a reasonable agreement with observations. The point source component (P) is picked out among nonidentified discrete gamma sources from EGRET catalog ...

Search for direct pair production of supersymmetric partners to the $${\uptau }_{}^{}$$ τ lepton in proton–proton collisions at $$\sqrt{s}=13\,\text {TeV} $$ s=13TeV

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
A search is presented for $${\uptau }_{}^{}$$ τ slepton pairs produced in proton–proton collisions at a center-of-mass energy of 13$$\,\text {TeV}$$ TeV . The search is carried out in events containing two $${\uptau }_{}^{}$$ τ leptons in the final state,

Neutralino dark matter in mSUGRA/CMSSM with a 125 GeV light Higgs scalar [PDF]

open access: yes, 2012
A bstractThe minimal supergravity (mSUGRA or CMSSM) model is an oft-used frame- work for exhibiting the properties of neutralino (WIMP) cold dark matter (CDM).

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.

Revisiting a Realistic Intersecting D6-Brane with Modified Soft SUSY Terms

open access: yesUniverse
Because there are a few typos in the supersymmetry-breaking sfermion masses and trilinear soft term, regarding the current Large Hadron Collider (LHC) and dark matter searches, we revisit a three-family Pati–Salam model based on intersecting D6-branes in

Dark matter in NMSSM with small λ and κ

open access: yesResults in Physics, 2023
The NMSSM provides an excellent dark matter candidate, usually the lightest neutralino (χ̃10) being the lightest supersymmetric particle (LSP), in the universe. It is a mixture of the bino, the neutral wino, the neutral higgsinos, and the singlino.

The R-parity violating decays of charginos and neutralinos in the B-L MSSM

open access: yesJournal of High Energy Physics, 2019
The B − L MSSM is the MSSM with three right-handed neutrino chiral multiplets and gauged B − L symmetry. The B − L symmetry is broken by the third family right-handed sneutrino acquiring a VEV, thus spontaneously breaking R-parity. Within a natural range

Searching for the Higgsino-Bino sector at the LHC

open access: yesJournal of High Energy Physics, 2020
We study the search for electroweakinos at the 13 TeV LHC in the case of heavy scalar superpartners. We consider both the direct production mode and the one associated with the decay of heavy Higgs bosons, and concentrate on the case of light Higgsinos ...
