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\mu^{+} \rightarrow e^{+} \gamma, μ+e+ee+\mu^{+} \rightarrow e^{+} e^{-} e^{+} and μNeN\mu^{-} N \rightarrow e^{-} N. The collection of upcoming experiments aim for sensitivity improvements up to 10410^{4} with respect to previous searches. The MEG II experiment, searching for μ+e+γ\mu^{+} \rightarrow e^{+} \gamma, 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+ee+\mu^{+} \rightarrow e^{+} e^{-} e^{+} with plans of physics data-taking as soon as 2025. The Mu2e and COMET experiments are upcoming searches for μNeN\mu^{-} N \rightarrow 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.
