Description
A compelling solution to the Dark Matter question is that DM particles are part of a “dark sector” with fields uncharged under the SM gauge group. On the other hand, conformal field theories are ubiquitous and appear as fixed points of gauge theories. CFTs are scale-invariant and UV complete. In this work, we consider dark sectors described by conformal field theories and couple to the SM via portal interactions. We make generic, model-independent predictions for the nature of dark matter, and show that light DM states are populated in the early universe via freeze-in in such models. The mass gap generated is directly proportional to the coupling to the SM.
