Light dark matter density distribution in the Sun

ORAL

Abstract

Weakly interacting massive particle (WIMP) is a popular dark matter candidate that can scatter with the nuclei of the Sun and lose energy. These WIMPs would then be captured and accumulate in the center of the Sun and annihilate to produce potentially detectable neutrino flux. This method, however, requires knowledge of the dark matter density distribution in the Sun after solar capture. In this case, we solve for the dark matter density distribution numerically taking into account evaporation, which has never been done before. The correct distribution is important for accurate inference in case of a detection from the Sun. In addition, a potential bound dark matter distribution outside the solar atmospheric, could allow for EM search of dark matter from the Sun.
