Abstract

We report on the status of charged lepton flavor violating (CLFV) experiments with muons. We focus on the three "golden channels": μ⁺ → e⁺ γ, μ⁺ → e⁺ e^- e⁺ and μ^- N → e^- N. The collection of upcoming experiments aim for sensitivity improvements up to 10⁴ with respect to previous searches. The MEG II experiment, searching for μ⁺ → e⁺ γ, is currently in its 4th year of physics data-taking with a published result from its first year of data. The Mu3e experiment is an upcoming experiment searching for μ⁺ → e⁺ e^- e⁺ with plans of physics data-taking as soon as 2025. The Mu2e and COMET experiments are upcoming searches for μ^- N → e^- N with the goal of physics data-taking starting in 2027 and 2026 respectively. This proceeding summarizes the signal signature, expected background, resolutions, and timelines for the mentioned searches.
