Indirect dark matter search with IceCube — •Li Ruohan, Stephan Meighen-Berger, and Anja Brenner — Technische Universität München, James-Franck-Straße 1, 85748, Garching, Germany

Dark Matter annihilation can generate standard particle pairs in primary and decay into neutrinos at the final state. Its spectrum can have a line shape in case of direct annihilation into neutrinos pair. IceCube neutrino observatory is a powerful instrument for indirect dark matter search because of its sensitivity to neutrinos energy of TeV to PeV. Its planned Upgrade can improve the dark matter nucleons interaction cross-section limits of one magnitude at lower energy. This talk will show a potential approach to test IceCube’s line-spectrum detection ability and estimate the conservative cross-section using both spin-independent and -dependent effective fields theory.
