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

Models for self-resonant dark matter

open access: yesJournal of High Energy Physics, 2022
Abstract We consider a new mechanism for enhancing the self-scattering and annihilation cross sections for dark matter with multiple components but without a light mediator. The lighter dark matter component plays a role of the u-channel pole in the elastic co-scattering for dark matter, leading to a large self-scattering cross ...

Scalar simplified models for dark matter [PDF]

open access: yesPhysical Review D, 2015
We introduce a set of minimal simplified models for dark matter interactions with the Standard Model, connecting the two sectors via either a scalar or pseudoscalar particle. These models have a wider regime of validity for dark matter searches at the LHC than the effective field theory approach, while still allowing straightforward comparison to ...

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 ...
