Description

Non-zero electric dipole moments (EDMs) of fundamental particles intrinsically violate time-reversal (T) and CP symmetries, providing a highly sensitive probe of physics beyond the Standard Model. This talk will present the muEDM experiment at the Paul Scherrer Institute (PSI), Switzerland, which aims to measure the muon EDM using the innovative frozen-spin technique within a compact storage trap. We will outline the fundamental principles of this search and present the status and conceptual design of the experimental setup for Phase I, targeting a sensitivity of $\sigma(d) \leq 4 \times 10^{-21} \, e \cdot \mathrm{cm}$, followed by a Phase II upgrade capable of reaching $\sigma(d) \leq 6 \times 10^{-23} \, e \cdot \mathrm{cm}$.
