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).

One-loop corrections to neutralino-stop coannihilation revisited [PDF]
, 2014 We discuss the ${\cal O}(\alpha_s)$ supersymmetric QCD corrections to neutralino-stop coannihilation into a top quark and a gluon in the Minimal Supersymmetric Standard Model (MSSM).

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 ...

Relic neutralino surface at a 100 TeV collider [PDF]
, 2014 We map the parameter space for minimal supersymmetric Standard Model neutralino dark matter which freezes out to the observed relic abundance, in the limit that all superpartners except the neutralinos and charginos are decoupled.

Naturalness of light neutralino dark matter in pMSSM after LHC, XENON100 and Planck data [PDF]
Journal of High Energy Physics, 2013 We examine the possibility of a light (below 46 GeV) neutralino dark matter (DM) candidate within the 19-parameter phenomenological Minimal Supersymmetric Standard Model (pMSSM) in the light of various recent experimental results, especially from the LHC,

Chargino and neutralino decays revisited [PDF]
The European Physical Journal C, 2001 We perform a comprehensive analysis of the decays of charginos and neutralinos in the Minimal Supersymmetric Standard Model where the neutralino $ _1^0$ is assumed to be the lightest supersymmetric particle. We focus, in particular, on the three-body decays of the next-to-lightest neutralino and the lightest chargino into the lightest neutralino and ...

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 ...
