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.

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.

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

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

Axion as a non-WIMP dark matter candidate [PDF]
, 2017 The axion arises in well-motivated extensions of the Standard Model of particle physics and is regarded as an alternative to the weakly interacting massive particle paradigm to explain the nature of dark matter.

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 Pions of a dark sector gauge group can be strongly interacting massive particle (SIMP) dark matter, produced by the freeze-out of 3 → 2 interactions, with naturally large self-interactions. We study if adding a dark photon to the set-up can do it all: i)

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.
