An observation of Charged Lepton Flavor Violation (CLFV) would be unambiguous evidence for physics beyond the Standard Model. The Mu2e and COMET experiments, under construction, are designed to push sensitivity CLFV in mu e conversion process unprecedented levels. Whether is observed or not, there a strong case made further improving sensitivity, examining on additional target materials. Mu2e-II proposed upgrade Mu2e, with at least an order magnitude rate over Mu2e. approach challenges this...

Should muon-to-electron conversion in the field of a nucleus be found current generation experiments, measurement atomic number dependence process will become an important experimental goal. We present new treatment (Z,A) coherent 236 isotopes. Our approach differs from previous treatments several ways. Firstly, we include effect permanent quadrupole deformation on charged lepton flavor violating matrix elements, using method Barrett moments. This also enables addition muonic X-ray nuclear...
The Snowmass report on rare processes and precision measurements recommended Mu2e-II a next generation muon facility at Fermilab (Advanced Muon Facility) as priorities for the frontier. Workshop future program FNAL was held in March 2023 to discuss design studies Mu2e-II, organizing efforts facility, identify synergies with other (e.g., collider). Topics included high-power targetry, status of R&D development compressor rings, FFA concepts experiments (conversion, decays, muonium...
