Abstract:

Dark matter may have its main appearance as macroscopic matter instead of a free particle state. In this talk, I will show that this could be true even in the simplest Higgs-portal dark matter model. The main form of dark matter is a non-topological soliton state with an energy density of the electroweak scale and a mass of one gram or above. The electroweak symmetry is unbroken inside this type of dark matter balls, which provides promising detection potential at experiments with a large-size detector.
