Yu Gao, Jason Kumar, and Danny Marfatia
TL;DR
This paper explores how neutrino detectors like IceCube/DeepCore can effectively detect isospin-violating dark matter interactions in the Sun, potentially rivaling direct detection experiments across various dark matter masses.
Contribution
It assesses the sensitivity of neutrino telescopes to isospin-violating dark matter, highlighting their competitive potential compared to direct detection methods.
Findings
IceCube/DeepCore can be competitive with direct detection experiments.
Sensitivity varies with dark matter mass and interaction type.
Neutrino detection offers a complementary approach to direct searches.
Abstract
We consider the prospects for studying spin-independent isospin-violating dark matter-nucleon interactions with neutrinos from dark matter annihilation in the Sun, with a focus on IceCube/DeepCore (IC/DC). If dark matter-nucleon interactions are isospin violating, IC/DC's reach in the spin-independent cross section may be competitive with current direct detection experiments for a wide range of dark matter masses. We also compare IC/DC's sensitivity to that of next generation argon, germanium, neon and xenon based detectors.
