Tools for Studying Low-Mass Dark Matter at Neutrino Detectors

Abstract

We determine the neutrino spectra arising from low-mass (4-10 GeV) dark matter annihilating in the sun. We also determine the low-mass dark matter capture rates (element by element in the sun), assuming dark matter interacts either through elastic contact interactions, elastic long-range interactions, or inelastic contact interactions. These are the non-detector-specific data needed for determining the sensitivity of a neutrino detector to dark matter annihilating in the sun. As an application, we estimate the sensitivity of a one kiloton liquid scintillation neutrino detector (such as KamLAND) and LBNE (LAr-based) to low-mass dark matter with long-range interactions and compare this to the expected CDMS sensitivity. It is found that KamLAND's sensitivity can exceed that obtainable from the current CDMS data set by up to two orders of magnitude.
