Description

We study the possibility for large volume underground neutrino experiments
to detect the neutrino flux from captured inelastic dark matter in the Sun.
The neutrino spectrum has two components: a mono-energetic "spike" from
pion and kaon decays at rest and a broad-spectrum "shoulder" from prompt
primary meson decays. We focus on detecting the shoulder neutrinos
from annihilation of hadrophilic inelastic dark matter with masses in the
range 4-100 GeV. We find the region of parameter space that these
neutrino experiments are more sensitive to than the direct-detection
experiments. For dark matter annihilation to heavy-quarks, the projected
sensitivity of DUNE is weaker than current (future) Super (Hyper) Kamiokande
experiments, while for the light-quark channel, only the spike is
observable and DUNE will be the most sensitive experiment.
