Natural Dark Matter from an unnatural Higgs boson and new colored particles at the TeV scale [PDF]
Journal of High Energy Physics, 2007 The thermal relic abundance of Dark Matter motivates the existence of new electroweak scale particles, independent of naturalness considerations. However, most unnatural Dark Matter models do not ensure the presence of new particles charged under SU(3)_C, resulting in challenging LHC phenomenology.

Prospects for determining the particle/antiparticle nature of WIMP dark matter with direct detection experiments [PDF]
Journal of High Energy Physics, 2017 Recientemente se señaló que las señales de detección directa de al menos tres objetivos diferentes se pueden utilizar para determinar si la partícula de materia oscura (DM) es diferente de su antipartícula. En este trabajo, examinamos en detalle la viabilidad de esta prueba en diferentes condiciones, motivados por propuestas para futuros detectores ...

Dark magnetic dipole property in fermionic absorption by nucleus and electrons
Journal 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
Journal 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

Associated production of neutrino and dark fermion at future lepton colliders
Journal of High Energy Physics, 2023 Fermionic dark matter can be pairly produced and hence searched with missing energy at colliders. We extend such probe to the associated production of a neutrino and a dark sector fermion at the future e + e − colliders such as CEPC, FCC-ee, ILC, and ...

A Dark-Matter Search Using the Final CDMS II Dataset and a Novel Detector of Surface Radiocontamination [PDF]
, 2012 Substantial evidence from galaxies, galaxy clusters, and cosmological scales suggests that ~85% of the matter of our universe is invisible. The missing matter, or "dark matter" is likely composed of non-relativistic, non-baryonic particles, which have ...

Stochastic fluctuations of bosonic dark matter [PDF]
, 2021 Numerous theories extending beyond the standard model of particle physics predict the existence of bosons that could constitute dark matter. In the standard halo model of galactic dark matter, the velocity distribution of the bosonic dark matter field ...

WIMP and FIMP dark matter in singlet-triplet fermionic model
Journal 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.
