The NMSSM dark sector constraints
EPJ 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.

Aspects of Moduli Stabilization in Type IIB String Theory
Advances in High Energy Physics, Volume 2016, Issue 1, 2016., 2016 We review moduli stabilization in type IIB string theory compactification with fluxes. We focus on KKLT and Large Volume Scenario (LVS). We show that the predicted soft SUSY breaking terms in KKLT model are not phenomenological viable. In LVS, the following result for scalar mass, gaugino mass, and trilinear term is obtained: m0 = m1/2 = −A0 = m3/2 ...

MSSM Dark Matter in Light of Higgs and LUX Results
Advances in High Energy Physics, Volume 2016, Issue 1, 2016., 2016 The constraints imposed on the Minimal Supersymmetric Standard Model (MSSM) parameter space by the Large Hadron Collider (LHC) Higgs mass limit and gluino mass lower bound are revisited. We also analyze the thermal relic abundance of lightest neutralino, which is the Lightest Supersymmetric Particle (LSP).

Phenomenological Hints from a Class of String Motivated Model Constructions
Advances in High Energy Physics, Volume 2015, Issue 1, 2015., 2015 We use string theory constructions towards the generalisation of the supersymmetric standard model of strong and electroweak interactions. Properties of the models depend crucially on the location of fields in extradimensional compact space. This allows us to extract some generic lessons for the phenomenological properties of the low energy effective ...

Neutralino annihilation into two photons [PDF]
Physics Letters B, 1997 We compute the annihilation cross-section of two neutralinos at rest into two photons, which is of importance for the indirect detection of neutralino dark matter in the galactic halo through a quasi-monochromatic gamma-ray line. We include all diagrams to one-loop level in the minimal supersymmetric extension of the standard model. We use the helicity

Journal 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.

Two Higgs Bosons near 125 GeV in the Complex NMSSM and the LHC Run I Data
Advances in High Energy Physics, Volume 2015, Issue 1, 2015., 2015 We analyse the impact of explicit CP‐violation in the Higgs sector of the Next‐to‐Minimal Supersymmetric Standard Model (NMSSM) on its consistency with the Higgs boson data from the Large Hadron Collider (LHC). Through detailed scans of the parameter space of the complex NMSSM for certain fixed values of one of its CP‐violating (CPV) phases, we obtain ...

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