Solar constraints on captured electrophilic dark matter

Abstract
Dark matter captured by interaction with electrons inside the Sun may annihilate via long-lived mediator to produce observable gamma ray signals. We utilize solar gamma ray flux measurements from the Fermi Large Area Telescope and the High Altitude Water Cherenkov observatory to put bounds on the dark matter electron-scattering cross section. We find that our limits are four to six orders of magnitude stronger than the existing limits for dark matter masses ranging between GeV to PeV scale.
