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 ...

On the change of old neutron star masses with galactocentric distance
, 2020 We show that the pulsar mass depends on the environment, and that it decreases going towards the center of the Milky Way. This is due to two combined effects, the capture and accumulation of self-interacting, non-annihilating dark matter by pulsars, and ...

Particle dark matter searches in the anisotropic sky [PDF]
, 2014 Anisotropies in the electromagnetic emission produced by dark matter annihilation or decay in the extragalactic sky are a recent tool in the quest for a particle dark matter evidence.

Search for Milli-Charged particles from the Sun at IceCube
Journal of High Energy Physics, 2022 It is assumed that heavy dark matter particles ϕ with O(TeV) mass captured by the Sun may decay to relativistic light milli-charged particles (MCPs). These MCPs could be measured by the IceCube detector.

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 ...

Ultra-Light Dark Matter in Ultra-Faint Dwarf Galaxies [PDF]
, 2016 Cold Dark Matter (CDM) models struggle to match the observations at galactic scales. The tension can be reduced either by dramatic baryonic feedback effects or by modifying the particle physics of CDM.

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.

Multilepton signatures from dark matter at the LHC
Journal of High Energy Physics, 2022 Leptonic signatures of Dark Matter (DM) are one of the cleanest ways to discover such a secluded form of matter at high energy colliders. We explore the full parameter space relevant to multi-lepton (2- and 3-lepton) signatures at the Large Hadron ...

Connecting neutrino physics with dark matter [PDF]
, 2014 The origin of neutrino masses and the nature of dark matter are two of the most pressing open questions of the modern astro-particle physics. We consider here the possibility that these two problems are related, and review some theoretical scenarios ...
