abstract
We carry out a detailed study of the confinement phase transition in a dark sector with a $SU(N)$ gauge group and a single generation of dark heavy quark. We focus on heavy enough quarks such that their abundance freezes out before the phase transition and the phase transition is of first-order. We find that during this phase transition the quarks are trapped inside contracting pockets of the deconfined phase and are compressed enough to interact at a significant rate, giving rise to a second stage of annihilation that can dramatically change the resulting dark matter abundance. As a result, the dark matter can be heavier than the often-quoted unitarity bound of $\sim100~$TeV. Our findings are almost completely independent of the details of the portal between the dark sector and the Standard Model. We comment briefly on possible signals of such a sector. Our main findings are summarized in a companion letter, while here we provide further details on different parts of the calculation.

Renormalon subtracted nonrelativistic QCD for heavy hadron systems
MRS-pNRQCD plus GFMC stabilizes heavy-hadron spectroscopy; NNLO baryon masses undershoot lattice QCD by 125–175 MeV with 1/m_Q scaling, and a critical mass ratio for tetraquark binding is extracted.

Primordial Black Hole from Tensor-induced Density Fluctuation: First-order Phase Transitions and Domain Walls
Tensor perturbations from FOPT and domain-wall sources are claimed to induce second-order scalar perturbations large enough to form primordial black holes, potentially all of the dark matter.

Prospecting bipartite Dark Matter through Gravitational Waves
A two-component dark matter model with an inert triplet scalar and a singlet fermion can explain the relic abundance while producing a strong electroweak phase transition and gravitational wave signals detectable by L...

What happens when supercooling is terminated by curvature flipping of the effective potential?
Supercooling terminated by curvature flipping still proceeds by bubble nucleation and expansion, not by smooth phase mixing, according to 3D lattice simulations.

Composite asymmetric dark matter with a dark photon portal: Multimessenger tests
Decaying composite dark matter in the 1 to 10 GeV mass range is most strongly constrained by AMS-02 positron data, needing lifetimes above roughly 10^26 seconds.

Noble Dark Matter: Surprising Elusiveness of Dark Baryons
Dark baryons made of SU(2)_L multiplet dark quarks are predicted to be dominated by an SU(2)_L singlet state above TeV masses, which strongly suppresses interactions with the Standard Model.

Populating dark sectors with relativistic bubble walls
Relativistic bubble walls can pair-produce dark matter much heavier than the phase transition scale, which then free-streams as warm dark matter.
