Description
In the context of Strongly Interacting Dark Matter theories dark isosinglet mesons might play an important role in the low-energy dynamics and might provide crucial signatures in collider and direct detection searches. We present first results in $Sp(4)$ gauge theory with $N_f=2$ fundamental Dirac flavours on the dark isosinglet pseudoscalar $\eta'$ and the isosinglet contribution to the dark $\pi^0$ meson in the case of strong isospin breaking. A preliminary investigation of the pion scattering lengths shows that the parameter space studied so far appears to be phenomenologically viable. Additionally, these results can be relevant to other BSM models such as composite Higgs scenarios.
