No dark matter neutrinos from the Sun appear in ten years of IceCube data, so the collaboration sets new world-leading upper limits on high-mass spin-dependent dark matter-nucleon scattering and on solar atmospheric neutrinos.

abstract
SIBYLL 2.1 is an event generator for hadron interactions at the highest energies. It is commonly used to analyze and interpret extensive air shower measurements. In light of the first detection of PeV neutrinos by the IceCube collaboration the inclusive fluxes of muons and neutrinos in the atmosphere have become very important. Predicting these fluxes requires understanding of the hadronic production of charmed particles since these contribute significantly to the fluxes at high energy through their prompt decay. We will present an updated version of SIBYLL that has been tuned to describe LHC data and extended to include the production of charmed hadrons.

Search for High-Energy Neutrinos From the Sun Using Ten Years of IceCube Data
No dark matter neutrinos from the Sun appear in ten years of IceCube data, so the collaboration sets new world-leading upper limits on high-mass spin-dependent dark matter-nucleon scattering and on solar atmospheric neutrinos.
