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 ...

Models for SIMP dark matter and dark photon
, 2015 We give a review on the SIMP paradigm and discuss a consistent model for SIMP dark mesons in the context of a dark QCD with flavor symmetry. The $Z'$-portal interaction is introduced being compatible with stable dark mesons and is responsible for making ...

Asymmetric Dark Matter from a GeV Hidden Sector [PDF]
, 2010 Asymmetric Dark Matter (ADM) models relate the dark matter density to the baryon asymmetry, so that a natural mass scale for ADM is around a few GeV.

A comprehensive approach to dark matter studies: exploration of simplified top-philic models [PDF]
, 2016 A bstractStudies of dark matter lie at the interface of collider physics, astrophysics and cosmology. Constraining models featuring dark matter candidates entails the capability to provide accurate predictions for large sets of observables and compare ...

Exclusion of leptophilic dark matter models using XENON100 electronic recoil data [PDF]
Science, 2015 Limiting unknows in the dark side Our knowledge of the inventory of stuff that makes up our universe amounts to a humbling 5%. The rest consists of either dark energy (~70%) or dark matter (~25%). Using atom interferometry, Hamilton et al.

Search for Composite Dark Matter with Optically Levitated Sensors. [PDF]
Physical Review Letters, 2020 Results are reported from a search for a class of composite dark matter models with feeble long-range interactions with normal matter. We search for impulses arising from passing dark matter particles by monitoring the mechanical motion of an optically ...

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)

ETHOS - An Effective Theory of Structure Formation: From dark particle physics to the matter distribution of the Universe [PDF]
, 2016 We formulate an effective theory of structure formation (ETHOS) that enables cosmological structure formation to be computed in almost any microphysical model of dark matter physics.

Simplified dark matter models for the Galactic Center gamma-ray excess [PDF]
, 2014 Motivated by the gamma-ray excess observed from the region surrounding the Galactic Center, we explore particle dark matter models that could potentially account for the spectrum and normalization of this signal.
