Dark matter from dynamical SUSY breaking

Understand

We consider explicit models of dynamical supersymmetry breaking where dark matter is a 10 -- 100 TeV strongly-interacting composite state carrying no standard model quantum numbers.

• These constructions are simple variants of well-known supersymmetry breaking mechanisms, augmented to allow for a large "flavor" symmetry.
• Dark matter is the lightest composite modulus charged under this symmetry and is a viable cold dark matter candidate with a thermal relic abundance.
• This is an attractive possibility in low-scale gauge-mediated scenarios where the gravitino is the lightest superparticle.
