abstract = {We present a minimal composite dark matter model, based on a SU(Nd) dark
sector with nf dark quarks and a heavy t-channel mediator. For nf ≥ 4, the dark favor
symmetry guarantees the stability of a subset of the dark pions, which serve as our dark
matter candidates. Their relic abundance is determined by dark sector annihilation with
the remaining dark pions, which are unstable and decay. Due to their degenerate masses,
the annihilation cross section is suppressed at low temperatures, thereby avoiding stringent
constraints from indirect detection and opening up the GeV mass window. The decaying dark
pions are naturally long lived. We obtain limits on the model from semi-visible or emerging
jet searches and estimate the reach of future probes.},
