We investigate the predictions of anomaly-free dark matter models for direct and indirect detection experiments. We focus on gauge theories where the existence of a fermionic dark matter candidate is predicted by anomaly cancellation, its mass is defined by the new symmetry breaking scale, and its stability is guaranteed by a remnant symmetry after the breaking of the gauge symmetry. We find an upper bound on the symmetry breaking scale by applying the relic density and perturbative constraints. The anomaly-free property of the theories allows us to perform a full study of the gamma lines from dark matter annihilation. We investigate the correlation between predictions for final radiation processes and gamma lines. Furthermore, we demonstrate that the latter can be distinguished from the continuum gamma ray spectrum.

  1. Probing mixed-state dark matter and flavor observables in a scalar-assisted baryonic gauge theory

    hep-ph 2026-02 reject novelty 5.0

    Adding a colored scalar S1 to a U(1)_B dark matter model correlates dark matter freeze-out with b→s μ+μ− observables, but the flavor amplitudes use a Z'–muon coupling that the model's zero-kinetic-mixing limit forbids.
