Prospects for determining the particle/antiparticle nature of WIMP dark matter with direct detection experiments [PDF]
Recientemente se señaló que las señales de detección directa de al menos tres objetivos diferentes se pueden utilizar para determinar si la partícula de materia oscura (DM) es diferente de su antipartícula. En este trabajo, examinamos en detalle la viabilidad de esta prueba en diferentes condiciones, motivados por propuestas para futuros detectores ...

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
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
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.

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
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

WIMP and FIMP dark matter in singlet-triplet fermionic model
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.

Strong gravitational lensing probes of the particle nature of dark matter
There is a vast menagerie of plausible candidates for the constituents of dark matter, both within and beyond extensions of the Standard Model of particle physics. Each of these candidates may have scattering (and other) cross section properties that are consistent with the dark matter abundance, BBN, and the most scales in the matter power spectrum ...

Revisiting the fermionic dark matter absorption on electron target
We perform a systematic study of the fermionic DM absorption interactions on electron target in the context of effective field theory. The fermionic DM absorption is not just sensitive to sub-MeV DM with efficient energy release, but also gives a unique ...

Fermionic dark matter in Dynamical Scotogenic Model
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 ...
