We fully explore the thermal freezeout histories of a vector-portal dark matter model, in the region of parameter space in which the ratio of masses of the dark photon $A^{\prime}$ and dark matter $\chi$ is in the range $1 \lesssim m_{A^{\prime}}/m_{\chi} \lesssim 2$. In this region $2 \rightarrow 2$ and $3 \rightarrow 2$ annihilation processes within the dark sector, as well as processes that transfer energy between the dark sector and the Standard Model, play important roles in controlling… Expand
Dark Matter Freeze-Out via Catalyzed Annihilation.
TLDR
A new paradigm of dark matter freeze-out is presented, where the annihilation of dark Matter particles is catalyzed, and the dark matter number density is depleted polynomially rather than exponentially (Boltzmann suppression) as in classical weakly interacting massive particles and strongly interactingmassive particles.

Dark matter freeze-in from semi-production
We study a novel dark matter production mechanism based on the freeze-in through semi-production, i.e. the inverse semi-annihilation processes. A peculiar feature of this scenario is that theExpand
Dark matter relic abundance beyond kinetic equilibrium
We introduce , a numerical precision tool for predicting the dark matter relic abundance also in situations where the standard assumption of kinetic equilibrium during the freeze-out process may notExpand
When freeze-out occurs due to a non-Boltzmann suppression: a study of degenerate dark sector
Exponential suppression or commonly known as the Boltzmann suppression in the number density of dark matter is the key ingredient for creating chemical imbalance prior to the usual thermalExpand

Enabling forbidden dark matter
The thermal relic density of dark matter is conventionally set by two-body annihilations. We point out that in many simple models, $3 \to 2$ annihilations can play an important role in determiningExpand
Refined bounds on MeV-scale thermal dark sectors from BBN and the CMB
New light states thermally coupled to the Standard Model plasma alter the expansion history of the Universe and impact the synthesis of the primordial light elements. In this work, we carry out anExpand
Dark Matter's secret liaisons: phenomenology of a dark U(1) sector with bound states
Dark matter (DM) charged under a dark U(1) force appears in many extensions of the Standard Model, and has been invoked to explain anomalies in cosmic-ray data, as well as a self-interacting DMExpand

Mechanism for thermal relic dark matter of strongly interacting massive particles.
TLDR
A new paradigm for achieving thermal relic dark matter is presented and 3→2 annihilations typically predict sizable 2→2 self-interactions which naturally address the "core versus cusp" and "too-big-to-fail" small-scale structure formation problems. Expand

TLDR
Proper treatment of the thermal averaging and the annihilation after freeze-out shows that the dip in relic abundance caused by a pole is not nearly as sharp or deep as previously thought. Expand
