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...

We propose a new mechanism where a multi-component dark sector generates the observed dark matter abundance and baryon asymmetry and thus addresses the coincidence between the two. The thermal freeze-out of dark matter annihilating into meta-stable dark partners sets the dark matter relic abundance while providing the out-of-equilibrium condition for baryogenesis. The meta-stable state...

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)...

We extend the thermal misalignment paradigm explored previously by my co-authors to include bosonic(Higgs) like degree of freedom in the thermal bath and explore how this will result in a thermally misalignment production of Ultra light dark matter scenarios.

We consider a scenario where the SM hypercharge field strength mixes with a rank-2 antisymmetric CFT operator. This mixing enables a freeze-in process in the early universe. At low-energies, the CFT confines; providing a dark sector described by dark "hadrons" which couples to the SM via a kinetically-mixed dark photon.
I will discuss why such a scenario is worth considering, the parameter...

We have proposed a dark matter candidate which is consistent with all current experiments, and observable in the near or foreseeable future through a wide variety of direct, indirect, and collider detection experiments [1,2]. This particle is unique in that it has (i) precisely defined couplings and (ii) a well-defined mass of about 72 GeV/c$^2$, providing specific cross-sections and other...

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...
