Research — Composite dark matter
Summary: It is a remarkable possibility that the dark matter discovered by many different observations of the large-scale universe could consist of composite particles that contain electrically charged constituents. These constituents interact with light but the composite particles they produce are dark, much like electrically charged quarks produce the electrically neutral neutron. Lattice calculations have provided predictions for how such composite dark matter may be seen in ongoing experiments using large underground detectors. Work is in progress to predict additional observable signatures of composite dark matter at high-energy particle colliders and future gravitational wave observatories.
Image: A cartoon showing how a neutral composite dark matter particle can interact with a nucleon by exchanging a photon that couples to the internal structure of the composite dark matter described by its electromagnetic form factors. Lattice calculations can predict such form factors and thereby the rate with which composite dark matter will interact to produce observable signatures in large underground detectors.
