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

Phenomenology of Dirac Neutralino Dark Matter [PDF]
, 2013 In supersymmetric models with an unbroken R-symmetry (rather than only R-parity), the neutralinos are Dirac fermions rather than Majorana. In this article, we discuss the phenomenology of neutralino dark matter in such models, including the calculation ...

Naturalness and dark matter in a realistic intersecting D6-brane model
Journal of High Energy Physics, 2018 We revisit a three-family Pati-Salam model with a realistic phenomenology from intersecting D6-branes in Type IIA string theory compactified on a T 6 /(ℤ2 × ℤ2) orientifold, and study its naturalness in view of the current LHC and dark matter searches ...

Light NMSSM neutralino dark matter in the wake of CDMS II and a 126 GeV Higgs boson [PDF]
, 2013 Recent results from the Cryogenic Dark Matter Search (CDMS) experiment have renewed interest in light (5{15 GeV) dark matter (DM) with a large spin-independent neutralino-nucleon scattering cross-section, SI & 10 42 cm 2 .

Coupled Boltzmann computation of mixed axion neutralino dark matter in the SUSY DFSZ axion model [PDF]
, 2013 The supersymmetrized DFSZ axion model is highly motivated not only because it offers solutions to both the gauge hierarchy and strong CP problems, but also because it provides a solution to the SUSY μ-problem which naturally allows for a Little Hierarchy.

10 GeV neutralino dark matter and light stau in the MSSM [PDF]
, 2013 It has recently been pointed out that a component of the observed gamma ray emission in the low-latitudes of Fermi Bubble has a spectral shape that can be explained by a 10 GeV dark matter (DM) annihilating to tau leptons with a cross-section of 2 x 10^{-

Physical Review DOne of the most well-founded candidates for dark matter remains a split-supersymmetry (SUSY) model with a Higgsino- or winolike lightest superpartner and the grander SUSY model providing answers for the hierarchy problem and grand unified theory scale unification.

THE NEUTRALINO MASS: CORRELATION WITH THE CHARGINOS [PDF]
Modern Physics Letters A, 2006 As the fundamental SU(2) supersymmetric parameters can be determined in the chargino sector, and the remaining fundamental parameters of the minimal supersymmetric extensions of the standard model can be analyzed in the neutralino sector, the two sectors can be correlated via these parameters.

Superheavy dark matter from string theory
Journal of High Energy Physics, 2021 Explicit string models which can realize inflation and low-energy supersymmetry are notoriously difficult to achieve. Given that sequestering requires very specific configurations, supersymmetric particles are in general expected to be very heavy ...

The birth and growth of neutralino haloes [PDF]
Monthly Notices of the Royal Astronomical Society, 2010 We use the Extended-Press-Schechter (EPS) formalism to study halo assembly histories in a standard $ $CDM cosmology. A large ensemble of Monte Carlo random walks provides the {\it entire} halo membership histories of a representative set of dark matter particles, which we assume to be neutralinos.
