Hadronic Footprint of GeV-Mass Dark Matter
arXiv:1911.11147 · doi:10.21468/SciPostPhys.8.6.092
Abstract
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.
