A hybrid type I + III inverse seesaw mechanism in U(1) R−L -symmetric MSSM
Journal of High Energy Physics, 2023 We show that, in a U(1) R−L -symmetric supersymmetric model, the pseudo-Dirac bino and wino can give rise to three light neutrino masses through effective operators, generated at the messenger scale between a SUSY breaking hidden sector and the visible ...

Studying squark mass spectrum through gluino decay at 100 TeV future hadron colliders
Physics Letters B, 2021 We study the prospect of determining the decay properties of the gluino in the supersymmetric (SUSY) standard model at a 100 TeV future hadron collider. We consider the case where the neutral Wino is the lightest superparticle.

Electroweak resummation of neutralino dark-matter annihilation into high-energy photons
Journal of High Energy Physics, 2023 We consider the resummation of large electroweak Sudakov logarithms for the annihilation of neutralino DM with (TeV) mass to high-energy photons in the minimal supersymmetric standard model, extending previous work on the minimal wino and Higgsino models.

The Discreet Charm of Higgsino Dark Matter: A Pocket Review
Advances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018 We give a brief review of the current constraints and prospects for detection of higgsino dark matter in low‐scale supersymmetry. In the first part we argue, after performing a survey of all potential dark matter particles in the MSSM, that the (nearly) pure higgsino is the only candidate emerging virtually unscathed from the wealth of observational ...

The last refuge of mixed wino-Higgsino dark matter [PDF]
Journal of High Energy Physics, 2016 We delineate the allowed parameter and mass range for a wino-like dark matter particle containing some Higgsino admixture in the MSSM by analysing the constraints from diffuse gamma-rays from the dwarf spheroidal galaxies, galactic cosmic rays, direct ...

Journal of Scientific Research in Science, 2022 The calculation of chargino-nutralino pair production at the LHC with √s = 14 TeV had been studied. Different benchmark points are evaluated for the chargino-nutralino pair production using MSSM for four conditions on mass parameters.

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).

Muon g − 2 anomaly in anomaly mediation
Journal of High Energy Physics, 2021 The long-standing muon g − 2 anomaly has been confirmed recently at the Fermilab. The combined discrepancy from Fermilab and Brookhaven results shows a difference from the theory at a significance of 4.2 σ. In addition, the LHC has updated the lower mass

Relic density of wino-like dark matter in the MSSM [PDF]
, 2016 A bstractThe relic density of TeV-scale wino-like neutralino dark matter in the MSSM is subject to potentially large corrections as a result of the Sommerfeld effect.

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 ...
