Description
The Muon g−2 experiment at Fermilab offers a unique opportunity to probe new physics beyond the Standard Model with unprecedented precision. This poster presents a novel search for ultralight scalar dark matter (DM), which could induce time-varying effects on the muon's anomalous precession frequency (ω_a) by modulating the muon mass. We construct an unevenly spaced time series of ω_a using the muon g-2 data and employ the Generalized Lomb-Scargle (GLS) periodogram to identify periodic signatures arising from scalar DM interactions. The analysis covers a broad frequency range corresponding to scalar DM masses between 10^-23 eV and 10^-13 eV. We introduce simulation-based techniques to validate the statistical behavior of the GLS power and to estimate global p-values under both null and signal hypotheses. These results constitute the first-ever direct search for dark matter using muons stored in a magnetic ring and serve as a pioneering effort toward future muon-philic dark matter searches.
