Recently, the IceCube Collaboration has published the results of their search for Dark Matter (DM) annihilations in the Sun. The analysis makes use of the fact that Dark Matter scattering off nuclei in the Sun could become gravitationally bound and subsequently self-annihilate into final states containing neutrinos. Assuming capture and annihilation rates are in equilibrium, upper bounds on the spin-independent (SI) and spin-dependent (SD) DM-Nucleus scattering cross sections have been derived. The bounds on the SD cross section are the most stringent to date, lowering previous bounds by up to one order of magnitude for DM masses larger than ∼ 100GeV. In this talk we explore the implications for theories beyond the Standard Model using the effective field theory approach. This approach allows us to compare the results with searches at the Large Hadron Collider and show the complementarity of these detection methods.
