Minimal model for dark matter and unification [PDF]

open access: yesPhysical Review D, 2006
Gauge coupling unification and the success of TeV-scale weakly interacting dark matter are usually taken as evidence of low energy supersymmetry (SUSY). However, if we assume that the tuning of the higgs can be explained in some unnatural way, from environmental considerations for example, SUSY is no longer a necessary component of any Beyond the ...

Model for neutrino masses and dark matter [PDF]

open access: yesPhysical Review D, 2003
We propose a model for neutrino masses that simultaneously results in a new dark matter candidate, the right-handed neutrino. We derive the dark matter abundance in this model, show how the hierarchy of neutrino masses is obtained, and verify that the model is compatible with existing experimental results.

Spintessence! New models for dark matter and dark energy

open access: yesPhysics Letters B, 2002
We investigate a class of models for dark matter and/or negative-pressure, dynamical dark energy consisting of ``spintessence,'' a complex scalar field $ $ spinning in a U(1)-symmetric potential $V( )=V(| |)$. As the Universe expands, the field spirals slowly toward the origin.

IceCube at the frontier of macroscopic dark matter direct detection

open access: yesJournal of High Energy Physics, 2022
For a class of macroscopic dark matter models, inelastic scattering of dark matter off a nucleus can generate electromagnetic signatures with GeV-scale energy.

Dark magnetic dipole property in fermionic absorption by nucleus and electrons

open access: yesJournal of High Energy Physics, 2022
The fermionic dark matter (DM) absorption by nucleus or electron targets provides a distinctive signal to search for sub-GeV DM. We consider a Dirac fermion DM charged under a dark gauge group and with the dark magnetic dipole operator.

Multi-component dark sectors: symmetries, asymmetries and conversions

open access: yesJournal of High Energy Physics, 2022
We study the relic abundance of several stable particles from a generic dark sector, including the possible presence of dark asymmetries. After discussing the different possibilities for stabilising multi-component dark matter, we analyse the final relic

Lighting up the LHC with Dark Matter

open access: yesJournal of High Energy Physics, 2023
We show that simultaneously explaining dark matter and the observed value of the muon’s magnetic dipole moment may lead to yet unexplored photon signals at the LHC.

WIMP and FIMP dark matter in singlet-triplet fermionic model

open access: yesJournal of High Energy Physics, 2022
We present an extension of the SM involving three triplet fermions, one triplet scalar and one singlet fermion, which can explain both neutrino masses and dark matter.
