Minimal asymptotically safe dark matter
We study a simple class of dark matter models with Nf copies of electroweak fermionic multiplets, stabilized by O(NF) global symmetry. Unlike conventional minimal dark matter which usually suffers from Landau poles, in these models the gauge coupling g2 has a non-trivial ultraviolet fixed point, and...
