Description
The axion, initially proposed to resolve the strong CP problem, has gained prominence as a compelling candidate for dark matter, particularly in its ultralight form. Recent theoretical studies, supported by simulations of cosmic evolution, indicate that dark matter axions may exist in a relatively higher mass range than previously explored. This development has catalyzed innovative proposals and experimental efforts to explore this promising parameter space. In this talk, I will provide an overview of the global experimental efforts in the search for high-mass dark matter axions, emphasizing key concepts and challenges.
