We propose a unique topological portal between quantum chromodynamics (QCD) and a dark sector characterized by a global symmetry breaking, which connects three QCD to two dark pions. When gauged, it serves as the leading portal between the two sectors, providing an elegant, self-consistent scenario of light thermal inelastic dark matter. The inherent antisymmetrization leads to diminished annihilations at later times and suppressed direct detection. However, novel collider signatures offer tremendous prospects for discovery at Belle II.

Darkly Charged ALPs
Darkly charged ALPs (DALPs) forbid all d=5 ALP-SM operators and admit only two leading d=6 operators (Higgs portal and hypercharge portal), with distinct collider, cooling, and dark-matter phenomenology.

The Dark Side of a Tera-Z Factory
Future Tera-Z runs at FCC-ee/CEPC could indirectly probe TeV-scale t-channel dark matter portals through one-loop and two-loop electroweak precision shifts, and in leptophilic models would be the only planned experime...

Sub-GeV dark matter and multi-decay signatures from dark showers at beam-dump experiments
SHiP could observe multiple displaced vertices per event from dark rho mesons in dark showers, probing dark rho masses up to ~2 GeV and discriminating the model from dark photons.

Topological Freeze-out by Semi-Annihilation
A dark QCD sector with gauged baryon number yields a p-wave semi-annihilation channel that can set the dark matter relic abundance for pion masses between 10 MeV and 1 TeV.
