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 $SU({N}_{D})$ strongly coupled theory with even ${N}_{D}\ensuremath{\ge}4$. All mass scales are technically natural, and dark matter stability is automatic without imposing an additional discrete or global symmetry. Constituent fermions transform in vectorlike representations of the …
