GeV-scale dark matter is an increasingly attractive target for direct detection, indirect detection, and collider searches. Its annihilation into hadronic final states produces a challenging zoo of light hadronic resonances. We update Herwig7 to study the photon and positron spectra from annihilation through a vector mediator. It covers dark matter masses between 250 MeV and 5 GeV and includes an error estimate. 
INTEGRAL x-ray constraints on sub-GeV dark matter
Light Dark Matter (DM), defined here as having a mass between 1 MeV and about 1 GeV, is an interesting possibility both theoretically and phenomenologically, at one of the frontiers of currentExpand
Indirect searches for dark matter bound state formation and level transitions
Indirect searches for dark matter (DM) have conventionally been applied to the products of DM annihilation or decay. If DM couples to light force carriers, however, it can be captured into boundExpand
Cosmological bounds on sub-GeV dark vector bosons from electromagnetic energy injection
New dark vector bosons that couple very feebly to regular matter can be created in the early universe and decay after the onset of big bang nucleosynthesis (BBN) or the formation of the cosmicExpand
Resonant sub-GeV Dirac dark matter
We study the phenomenology and detection prospects of a sub-GeV Dirac dark matter candidate with resonantly enhanced annihilations via a dark photon mediator. The model evades cosmologicalExpand


Novel Spectral Features in MeV Gamma Rays from Dark Matter
Astrophysical searches for gamma rays are one of the main strategies to probe the annihilation or decay of dark matter particles.We present a new class of distinct sub-GeV spectral features thatExpand
Probing leptophilic dark sectors with hadronic processes
We study vector portal dark matter models where the mediator couples only to leptons. In spite of the lack of tree-level couplings to colored states, radiative effects generate interactions withExpand
Radiative Processes in Dark Matter Photino Annihilation
Abstract It is shown that radiative corrections to the photino annihilation process gggg→e + e − in the galactic halo can be enormous, with the radiative process being several orders of magnitudeExpand
Radiative processes in LSP annihilation
Abstract We calculate the O(α) corrections to the annihilation cross section for dark matter candidates in the minimal supersymmetric standard model. In particular, the radiative process χχ→q q g isExpand
Low-Mass Dark Matter Search with the DarkSide-50 Experiment.
We present the results of a search for dark matter weakly interacting massive particles (WIMPs) in the mass range below 20  GeV/c^{2} using a target of low-radioactivity argon with a 6786.0 kg dExpand
Antiproton constraints on dark matter annihilations from internal electroweak bremsstrahlung
If the dark matter particle is a Majorana fermion, annihilations into two fermions and one gauge boson could have, for some choices of the parameters of the model, a non-negligible cross-section.Expand
Hazma: a python toolkit for studying indirect detection of sub-GeV dark matter
With several proposed MeV gamma-ray telescopes on the horizon, it is of paramount importance to perform accurate calculations of gamma-ray spectra expected from sub-GeV dark matter annihilation andExpand
On the importance of electroweak corrections for Majorana dark matter indirect detection
Recent analyses have shown that the inclusion of electroweak corrections can alter significantly the energy spectra of Standard Model particles originated from dark matter annihilations. WeExpand

TASI lectures on dark matter models and direct detection
These lectures provide an introduction to models and direct detection of dark matter. We summarize the general features and motivations for candidates in the full dark matter mass range, and thenExpand
