Identifying Minimal Composite Dark Matter

Abstract

We attempt to identify the minimal composite scalar dark matter from strong dynamics with the characteristic mass of order TeV scale. We provide direct and indirect limits from dark matter direct detections and collider facilities. Compared to a fundamental scalar dark matter, our results show that in the composite case with sizable derivative interaction between the dark matter and Higgs, the disappearing resonant mass region, the smaller spin-independent dark matter-nucleon scattering cross section in certain dark mass region, and the absence at the HL-LHC provide us an opportunity to distinguish the composite dark matter.
