Description
In this talk, we propose a model for a dark matter (and dark sector) which is in complete decoupling with the Standard model sector. In an effort to identify DM's stability, mass and interaction type it does, we pay a special attention to two arguments that concern the Hubble tension and the core-cusp problem. Thereby, we aim at presenting a possibility of having a light decaying fermion DM which has both a theoretical and phenomenological appealing aspects.
