In this paper we present Super-Resonant Dark Matter (SRDM), a model of self-interacting dark matter (SIDM) based on the low energy effective theory of supersymmetric QCD. A novel feature of the model is that an s-channel resonance is generated in the non-relativistic limit via a mass ratio fixed by flavor symmetry. One loop corrections shift the mass ratio off resonance and allow SRDM to...
A novel dark matter candidate is proposed, arising from spontaneously breaking of the twin color group in the fraternal twin Higgs scenario. A matter/antimatter asymmetry is co-generated in both sectors from the sources of the twin color breaking. A quark that is singlet under the residual twin color group decay into a colorless twin quark and twin lepton, which are consisted of asymmetric...
It is often said that asymmetric dark matter is light compared to typical weakly interacting massive particles. Here we point out a simple scheme with a neutrino portal and $\mathcal{O}(60 \text{ GeV})$ asymmetric dark matter which may be ``added'' to any standard \bs{electroweak} baryogenesis scenario. The dark sector contains a copy of the Standard Model gauge group, as well as (at least)...
The addition of spatial dimensions compactified to submillimeter scales serves as an elegant solution to the hierarchy problem. As a consequence of such large extra dimensions, is the possibility of producing primordial black holes (PBHs) from high-energy collisions in the early universe, leading to a novel source of dark matter. While four-dimensional PBHs have been extensively studied, they...
