We have a great mathematical model for how the known elementary particles interact, but there are phenomena such as dark matter that it doesn't explain. New particles light enough to be created at accelerators could resolve many of these issues, but could exist anywhere across a very wide range of masses and behaviours. Accordingly, physicists are using many different experiments to search for them, each optimised for a different target. This colloquium will discuss the motivation for new bosons interacting with the dark sector and introduce two very different experiments searching for them: ATLAS, at the 13 TeV LHC, and DarkLight, at the 30 MeV ARIEL accelerator at TRIUMF.
