The existence of a SM-neutral and light dark sector coupled to the visible sector via irrelevant portal interactions was considered in $2012.08537$. Such scenarios tend to be common in dark matter models arising as various extensions of the Standard Model.
The authors of $2012.08537$ use the conformal behaviour of this dark sector at energies $\Lambda_{IR} << E << \Lambda_{UV}$ to study their phenomenology in a model independent way, where $\Lambda_{UV}$ is the scale at which the heavy mediator exchange generates the portal operators and $\Lambda_{IR}$ is the infrared scale.
Our work extends the work of $2012.08537$ as we derive bounds from various classes of future facilities aimed at detecting long lived particles (transverse detectors like MATHUSLA, CODEX-b etc. as well as fixed target experiments like SHiP etc.) to complement the bounds obtained in $2012.08537$ by showing an improved reach on small $\Lambda_{IR}$.
We hope this study would encourage that future experimental analyses be performed for generic dark sectors without a focus on a particular benchmark model.
