Abstract: I will consider scenarios where dark matter interacts with Standard Model states via the exchange of a light pseudoscalar. While there are typically only weak constraints from direct dark matter searches, the pseudoscalar mediator will induce flavour-changing interactions in the Standard Model, providing a promising alternative way to test these models. I will present the constraints arising from rare meson decays and fixed target experiments and show that the resulting bounds are highly complementary to the information inferred from the dark matter relic density and the constraints from primordial nucleosynthesis. These findings have important implications for the dark matter self-interaction cross section and the prospects of probing dark matter coupled to a light pseudoscalar with direct or indirect detection experiments.
