Description

I 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 flavor symmetry guarantees the stability of a subset of the dark pions, which serve as dark matter candidates. Their relic abundance is determined by 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 leading to exotic collider signatures, e.g. semi-visible and emerging jets.
