Toward (finally!) ruling out Z and Higgs mediated dark matter models [PDF]
, 2016 In recent years, direct detection, indirect detection, and collider experiments have placed increasingly stringent constraints on particle dark matter, exploring much of the parameter space associated with the WIMP paradigm.

Simplified models vs. effective field theory approaches in dark matter searches [PDF]
, 2016 In this review we discuss and compare the usage of simplified models and Effective Field Theory (EFT) approaches in dark matter searches. We provide a state of the art description on the subject of EFTs and simplified models, especially in the context of

Review of strongly-coupled composite dark matter models and lattice simulations [PDF]
, 2016 We review models of new physics in which dark matter arises as a composite bound state from a confining strongly-coupled non-Abelian gauge theory. We discuss several qualitatively distinct classes of composite candidates, including dark mesons, dark ...

Constraints on low-mass, relic dark matter candidates from a surface-operated SuperCDMS single-charge sensitive detector [PDF]
Physical Review D, 2020 This article presents an analysis and the resulting limits on light dark matter inelastically scattering off of electrons, and on dark photon and axion-like particle absorption, using a second-generation SuperCDMS high-voltage eV-resolution detector. The

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 ...

Non-cold dark matter from primordial black hole evaporation [PDF]
Journal of Cosmology and Astroparticle Physics, 2020 Dark matter coupled solely gravitationally can be produced through the decay of primordial black holes in the early universe. If the dark matter is lighter than the initial black hole temperature, it could be warm enough to be subject to structure ...

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.

Imprints of dark matter on black hole shadows using spherical accretions [PDF]
The European Physical Journal C, 2020 We study the possibility of identifying dark matter in the galactic center from the physical properties of the electromagnetic radiation emitted from an optically-thin disk region around a static and spherically symmetric black hole.

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.
