Flavor physics offers a promising way to explore fundamental aspects of the standard model, such as the mass hierarchy and electroweak symmetry breaking. Within this field, Charged Lepton Flavor Violation (CLFV) stands out as a phenomenon that is strongly suppressed in the Standard Model, making it an excellent probe for potential new physics. Ongoing CLFV experiments, including Mu2e, COMET, MEG, and Mu3e, are preparing for data collection in the coming decade. Among the possible searches in the muon sector (𝜇 → 𝑒𝛾, mu3e and muon conversion), two muon conversion experiments will start taking data in few years: Mu2e at Fermilab and COMET at JPArk. Both of them aim to improve the current sensitivity by several orders of magnitude. This violation of charged lepton flavor presents an opportunity to explore novel physics on a scale not currently accessible through direct searches at contemporary or planned high-energy colliders.
