Simplified models of light new physics provide a convenient benchmark for experimental searches for new physics signatures, including dark matter. However, in less simplified – and more realistic – scenarios invoking additional degrees of freedom additional modes of detection may arise. In this study, we examine a model in which the dark sector couples to the Standard Model sector via a light dark Higgs boson portal but it also contains a secluded scalar dark matter candidate with the mass around the TeV scale. In this model, involving both light and heavy particles in the dark sector, we find some new interesting phenomenological features that allow one to avoid otherwise stringent cosmological bounds and lead to new complementary probes in intensity frontier searches for light long-lived particles, in indirect detection searches for dark matter and cosmic microwave background surveys. We also highlight possible non-local effects present in the indirect detection searches for dark matter that could significantly affect usual detection strategies and allow one to distinguish this model from the usual signatures based on simplified models.
