The authors present an approach for detecting ultralight bosonic dark matter using collider and beam dump experiments. The method relies on the time-varying mass of dark sector mediators, which serve as a portal between the dark and Standard Model sector. CMS Open Data are used to demonstrate that this method enhances sensitivity by around one order of magnitude compared to the double-peak method.
