Searching for inelastic dark matter with future LHC experiments

open access: yesJournal of High Energy Physics, 2022
We consider a dark sector containing a pair of almost degenerate states coupled to the Standard Model through a dark photon mediator. This set-up constitutes a simple realization of the inelastic dark matter scenario.

Distinguishing two dark matter component particles at e + e − colliders

open access: yesJournal of High Energy Physics, 2022
We investigate ways of identifying two kinds of dark matter (DM) component particles at high-energy colliders. The strategy is to notice and distinguish double-peaks(humps) in the missing energy/transverse energy distribution.

Charged dark matter in supersymmetric twin Higgs models

open access: yesJournal of High Energy Physics, 2022
Supersymmetric Twin Higgs models ameliorate the fine-tuning of the electroweak scale originating from the heavy scalar top partners required by the non-discovery of them at the Large Hadron Collider. If the Lightest Supersymmetric Particle resides in the

Super-resonant dark matter

open access: yesJournal of High Energy Physics, 2022
We introduce Super-Resonant Dark Matter, a model of self-interacting dark matter based on the low energy effective theory of supersymmetric QCD. The structure of the theory ensures a resonant enhancement of the self-interactions of the low energy mesons,

Anapole moment of Majorana fermions and implications for direct detection of neutralino dark matter

open access: yesJournal of High Energy Physics, 2023
For Majorana fermions the anapole moment is the only allowed electromagnetic multipole moment. In this work we calculate the anapole moment induced at one-loop by the Yukawa and gauge interactions of a Majorana fermion, using the pinch technique to ...

Minimal consistent Dark Matter models for systematic experimental characterisation: fermion Dark Matter

open access: yesJournal 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

open access: yesJournal 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

open access: yesJournal 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.

The continuum dark matter zoo

open access: yesJournal 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 ...

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.
