Novel constraints on the particle nature of dark matter from stellar streams [PDF]
Journal of Cosmology and Astroparticle Physics, 2021 Tidal streams are highly sensitive to perturbations from passing dark matter (DM) subhalos and thus provide a means of measuring their abundance. In a recent paper, we analyzed the distribution of stars along the GD-1 stream with a combination of data from the Gaia satellite and the Pan-STARRS survey, and we demonstrated that the population of DM ...

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.

Gamma-ray lines may reveal the CP nature of the dark matter particle [PDF]
Journal of Cosmology and Astroparticle Physics, 2019 Determining the fundamental properties of the dark matter is one of the most important open problems in particle physics today. If the dark matter particle has spin zero, one of these properties is its CP nature. That is, whether it is CP-even (scalar), CP-odd (pseudoscalar), or if its interactions violate CP.

Revisiting the fermionic dark matter absorption on electron target
Journal of High Energy Physics, 2022 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 ...

Prospects for determining the particle/antiparticle nature of WIMP dark matter with direct detection experiments [PDF]
Journal of High Energy Physics, 2017 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 ...

Fermionic dark matter in Dynamical Scotogenic Model
Journal 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 ...

The Migdal effect in semiconductors for dark matter with masses below ∼ 100 MeV
Journal of High Energy Physics, 2023 Dark matter scattering off a nucleus has a small probability of inducing an observable ionization through the inelastic excitation of an electron, called the Migdal effect.

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)
