Light NMSSM neutralino dark matter in the wake of CDMS II and a 126 GeV Higgs boson [PDF]

open access: yes, 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 .

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”.

10 GeV neutralino dark matter and light stau in the MSSM [PDF]

open access: yes, 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^{-

Superheavy dark matter from string theory

open access: yesJournal 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 ...

Neutralino-neutralino annihilation to photon and gluon pairs in MSSM models [PDF]

open access: yesPhysical Review D, 2004
The complete 1-loop computation of the processes $(\tchi^0_i \tchi^0_j \leftrightarrow , ~ gg)$, for any pair of the four MSSM neutralinos, has been performed for an arbitrary c.m energy. As a first application suitable for Dark Matter (DM) searches, the neutralino-neutralino annihilation is studied at relative velocities $v/c\simeq 10^{-3 ...

Search for new physics in events with two soft oppositely charged leptons and missing transverse momentum in proton–proton collisions at s=13TeV

open access: yesPhysics Letters B, 2018
A search is presented for new physics in events with two low-momentum, oppositely charged leptons (electrons or muons) and missing transverse momentum in proton-proton collisions at a centre-of-mass energy of 13 TeV.

Neutrinos for TeV neutralinos

open access: yesPhysical Review D
One 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.
