Linear sigma dark matter
Abstract We present a model of self-interacting dark matter based on QCD-like theories and inspired by the proximity of a 0(980 ± 20) to the K K ¯ $$ K\overline{K} $$ (990) threshold. Dark matter is comprised of dark pions which self-scatter via the σ resonance close to the ππ threshold. While the l...

| description | Abstract We present a model of self-interacting dark matter based on QCD-like theories and inspired by the proximity of a 0(980 ± 20) to the K K ¯ $$ K\overline{K} $$ (990) threshold. Dark matter is comprised of dark pions which self-scatter via the σ resonance close to the ππ threshold. While the linear sigma model serves as a qualitative guide, a fully unitary description of the scattering in the strongly coupled regime is given by effective range theory. The introduction of a kinetically mixed dark photon allows the dark pion to either freeze-out or -in. We study the viable parameter space which explains the observed relic abundance while evading all current constraints. Searches for dark matter self interactions at different scales, (in)direct detection signals, and (in)visibly-decaying dark photons will test this model in the near future. |
