Experimental evidence points to the existence of Dark Matter that makes up a 85% of all mass but does not interact with ordinary matter except through gravity. Many experiments are underway to shed light on this so-called “Dark Sector” of physics, using various techniques and technologies to probe for signs of new particles or new interactions. In this talk, I will focus on one possible realisation of a Dark Sector: An additional dark Higgs Boson with a mass in the MeV to GeV-range as possible portal to Dark Matter. I will review the very latest results from Belle II that involve long-lived particles or fully invisible final states, produced in rare b→s transitions. I will put these results into context with direct detection dark matter experiments and LHC results, and discuss the Dark Higgs frontier at the next generation experiment SHiP.
