Query: On Anomaly-Free Dark Matter Models   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.
