Dark matter searches in the Galactic Center with IceCube-DeepCore and IceCube-Upgrade

The nature of Dark Matter is one of the important unresolved questions in fundamental physics. It is assumed in many Beyond Standard Model theories that dark matter candidates can have weak coupling to Standard Model (SM) particles. In heavy cosmological objects, like galaxies, the Sun, or the Earth, dark matter can be gravitationally accumulated in high abundance. Then, the DM can decay or annihilate into the anomalous flux of SM particles detectable by various detector types. In this contribution, I will present a recent search for neutrino signals from GeV-scale Dark Matter in the Galactic Center with the IceCube-DeepCore. I will also discuss the prospect of such a search with the IceCube-Upgrade, an upcoming extension of the IceCube Neutrino Observatory to enhance performance in the GeV energy range.
