Nonperturbative investigations of SU(3) gauge theory with eight dynamical flavors

We present our lattice studies of SU(3) gauge theory with Nf=8 degenerate fermions in the fundamental representation. Using nHYP-smeared staggered fermions we study finite-temperature transitions on lattice volumes as large as L3×Nt=483×24, and the …

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 …
