Dark matter charged under a new gauge sector, as motivated by recent data, suggests a rich
GeV-scale “dark sector” weakly coupled to the standard model by gauge kinetic mixing. The …

We investigate the possibility that dark matter could be made of scalar candidates and focus,
in particular, on the unusual mass range between a few MeVs and a few GeVs. After …

Stable dark matter particles may arise as pseudo-Goldstone bosons from the confinement of
dark quarks interacting via a non-Abelian gauge force. Their relic abundance is determined …

In a broad class of consistent models, MeV to few-GeV dark matter interacts with ordinary
matter through weakly coupled GeV scale mediators. We show that a suitable meter scale …

Despite mounting evidence that dark matter (DM) exists in the Universe, its fundamental
nature remains unknown. We present sensitivity estimates to detect DM particles with a …

We consider a simple class of models in which the dark matter, X, is coupled to a new gauge
boson, ϕ, with a relatively low mass (m ϕ∼ 100 MeV–3 GeV). Neither the dark matter nor …

We revisit the possibility of light-scalar dark matter, in the MeV to GeV mass bracket and
coupled to electrons through fermion or vector mediators, in light of significant experimental …

A fraction of the dark matter may consist of a particle species that interacts much more
strongly with the Standard Model than a typical weakly interacting massive particle (WIMP) …

A number of theories, spanning a wide range of mass scales, predict dark matter candidates
that have lifetimes much longer than the age of the Universe, yet may produce a significant …

We propose that dark matter is composed of particles that naturally have the correct thermal
relic density, but have neither weak-scale masses nor weak interactions. These models …
