Detecting Stealth Dark Matter Directly through Electromagnetic Polarizability

We calculate the spin-independent scattering cross section for direct detection that results from the electromagnetic polarizability of a composite scalar “stealth baryon” dark matter candidate, arising from a dark SU(4) confining gauge …

Stealth Dark Matter: Dark scalar baryons through the Higgs portal

We present a new model of stealth dark matter: a composite baryonic scalar of an SU(ND) strongly coupled theory with even ND≥4. All mass scales are technically natural, and dark matter stability is automatic without imposing an additional discrete or …
