Journal of High Energy Physics, 2022 The search for a Dark Matter particle is the new grail and hard-sought nirvana of the particle physics community. From the theoretical side, it is the main challenge to provide a consistent and model-independent tool for comparing the bounds and reach of

Asymmetries in extended dark sectors: a cogenesis scenario
Journal of High Energy Physics, 2023 The observed dark matter relic abundance may be explained by different mechanisms, such as thermal freeze-out/freeze-in, with one or more symmetric/asymmetric components. In this work we investigate the role played by asymmetries in determining the yield

The Z 7 model of three-component scalar dark matter
Journal of High Energy Physics, 2023 We investigate, for the first time, a scenario where the dark matter consists of three complex scalar fields that are stabilized by a single Z 7 symmetry.

Journal of High Energy Physics, 2023 We generalize the recently proposed continuum dark matter model to the case where the dark matter consists of a spin-1/2 or spin-1 gapped continuum. We construct simple continuum analogs of weakly interacting massive particles annihilating through the Z ...

Unraveling the Scotogenic model at muon collider
Journal of High Energy Physics, 2022 The Scotogenic model extends the standard model with three singlet fermion N i and one inert doublet scalar η to address the common origin of tiny neutrino mass and dark matter. For fermion dark matter N 1, a hierarchical Yukawa structure ∣ y 1 e ∣ ≪ ∣ y

IceCube at the frontier of macroscopic dark matter direct detection
Journal 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
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 ...

Particle dark matter searches in the anisotropic sky [PDF]
, 2014 Anisotropies in the electromagnetic emission produced by dark matter annihilation or decay in the extragalactic sky are a recent tool in the quest for a particle dark matter evidence.
