Dark matter likelihoods

IceCube has developed an improved event-level likelihood formalism for including neutrino telescope data in global fits for new physics. This was used to derive limits on spin-dependent dark matter-proton scattering with 79-string IceCube data. These results were announced by the IceCube Collaboration on January 5, 2016. The collaboration also provides nulike, a tool for computing unbinned, model-independent likelihoods from IceCube searches for dark matter annihilation in the Sun.
