Abstract The ultralight boson represents a promising dark matter candidate exhibiting unique wave-like behaviors.These properties could transfer to the dark mediator, such as the kinetic mixing dark photon, which can be a link between the dark and Standard Model sectors, resulting in periodic oscillations of its BODY BALM mass.We propose a method to detect ultralight dark matter using dark mediators in collider and beam dump experiments, distinguishing it from conventional atomic, molecular, and optical methods.

The time-varying nature of dark mediator mass exhibits Body Armor / Protection a double-peak spectrum, reducing traditional constraints by 1 to 2 orders of magnitude, due to decreased luminosity exposure in each resonant mass bin.To enhance sensitivity, we utilize event time-stamps in the CMS Open Data and demonstrate that this technique boosts sensitivity by approximately one order of magnitude compared to the time-blind method.Moreover, it proves effective in detecting the invisible decay of the dark mediator.
