Description
Solar atmospheric neutrinos are produced in the high energy cascades that follow
cosmic ray interactions with the outer parts of the Sun. We perform an updated
calculation of the solar atmospheric neutrino flux and discuss the impact on searches
for neutrinos from annihilations of weakly interacting massive particles (WIMPs). Our
code is event-based and publicly available, and thus suitable for experiments. We find
that about 2-3 solar atmospheric neutrino events per year are expected in an
IceCube-like detector, generally higher than the Earth atmospheric neutrino flux per
solid angle. The solar atmospheric neutrino flux can furthermore, although small, be a
difficult background for solar WIMP searches as spectral differences can be challenging
to distinguish with current neutrino telescopes.
