The NMSSM dark sector constraints

open access: yesEPJ Web of Conferences, 2017
In this paper authors present review of neutralino research results in LHC, cosmological observations and theoretical models. Nowdays there are constraints on the mass of dark matter particle from experiments.

Combined searches for the production of supersymmetric top quark partners in proton–proton collisions at $$\sqrt{s} = 13\,\text {Te}\text {V} $$ s = 13 Te

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
A combination of searches for top squark pair production using proton–proton collision data at a center-of-mass energy of 13 $$\,\text {Te}\text {V}$$ Te at the CERN LHC, corresponding to an integrated luminosity of 137 $$\,\text {fb}^{-1}$$ fb - 1 ...

TeV SUSY dark matter confronted with the current direct and indirect detection data

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
In the minimal supersymmetric standard model (MSSM) the lightest superparticle (LSP) can be a TeV neutralino (mainly dominated by higgsino or wino) which serves as a dark matter candidate with correct thermal relic density. In this work we confront the 1–

Dark matter in the KL moduli stabilization scenario with SUSY breaking sector from N $$ \mathcal{N} $$ = 1 SQCD

open access: yesJournal of High Energy Physics, 2019
We investigate neutralino dark matter from a string/M-theory perspective. Using the Kallosh-Linde (KL) scenario to stabilize the string moduli requires supersymmetry breaking for uplifting to a de Sitter vacuum.

Searching for light neutralinos with a displaced vertex at the LHC

open access: yesJournal of High Energy Physics, 2022
We study a bino-like light neutralino ( χ ~ 1 0 $$ {\overset{\sim }{\chi}}_1^0 $$ ) produced at the LHC from the decay of a scalar lepton ( e ~ L $$ \tilde{e}_L $$ ) through the process pp → e ~ L $$ \tilde{e}_L $$ → e χ ~ 1 0 $$ e{\overset{\sim }{\chi ...

R-parity violating decays of Bino neutralino LSPs at the LHC

open access: yesJournal of High Energy Physics, 2019
The R-parity violating decays of Bino neutralino LSPs are analyzed within the context of the B − L MSSM “heterotic standard model”. These LSPs correspond to statistically determined initial soft supersymmetry breaking parameters which, when evolved using

Muon $$\mathbf {g-2}$$ g - 2 , neutralino dark matter and stau NLSP

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
We explore the implications of resolving the muon $$g-2$$ g - 2 anomaly in a $$SU(4)_c \times SU(2)_L \times SU(2)_R$$ S U ( 4 ) c × S U ( 2 ) L × S U ( 2 ) R model, where the soft supersymmetry breaking scalar and gaugino masses break the left-right (LR)

b − τ Yukawa unification in SUSY SU(5) with mirage mediation: LHC and dark matter implications

open access: yesJournal of High Energy Physics, 2019
We consider a class of b − τ Yukawa unified Supersymmetric (SUSY) SU(5) GUTs, in which the asymptotic gaugino M 1,2,3 masses are generated through the mirage mediated supersymmetry breaking, which is a combination of the gravity and anomaly mediation ...

Explaining muon $${g}-2$$ g - 2 data in the $$\mu \nu $$ μ ν SSM

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
We analyze the anomalous magnetic moment of the muon $$g-2$$ g - 2 in the $$\mu \nu $$ μ ν SSM. This R-parity violating model solves the $$\mu $$ μ problem reproducing simultaneously neutrino data, only with the addition of right-handed neutrinos. In the

R-parity violating decays of Wino chargino and wino neutralino LSPs and NLSPs at the LHC

open access: yesJournal of High Energy Physics, 2019
The R-parity violating decays of both Wino chargino and Wino neutralino LSPs are analyzed within the context of the B − L MSSM “heterotic standard model”.
