Fermionic dark matter in Dynamical Scotogenic Model [PDF]

open access: diamondJournal of High Energy Physics, 2023
In the Dynamical Scotogenic Model, the global B − L symmetry is supposed to be broken spontaneously resulting in a massless Goldstone boson called majoron, and massive right handed neutrinos which participate in the generation of light neutrino massses ...

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

Scalar Simplified Models for Dark Matter [PDF]

open access: yes, 2014
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.

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 ...

Simplified models for dark matter face their consistent completions. [PDF]

open access: yes, 2016
Simplified dark matter models have been recently advocated as a powerful tool to exploit the complementarity between dark matter direct detection, indirect detection and LHC experimental probes.

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,

Empirical Models for Dark Matter Halos. I. Nonparametric Construction of Density Profiles and Comparison with Parametric Models [PDF]

open access: yes, 2005
We use techniques from nonparametric function estimation theory to extract the density profiles, and their derivatives, from a set of N-body dark matter halos.

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 ...
