TL;DR: The Mu2e experiment at Fermilab will search for charged lepton flavor violation via the coherent conversion process with a sensitivity approximately four orders of magnitude better than the current world's best limits for this process.

TL;DR: Mu2e as discussed by the authors is a new experiment to search for charged lepton flavor violation with unprecedented sensitivity, which is almost a four order-of-magnitude improvement over the existing limit.

TL;DR: Mu2e-II as discussed by the authors proposes an evolution of the Mu2e experiment, which would leverage advances in detector technology and utilize the increased proton intensity provided by the Fermilab PIP-II upgrade to improve the sensitivity for neutrinoless muon-to-electron conversion.

TL;DR: In this article, a conceptual design for the magnetic system which meets the Fermilab Mu2e experiment requirements is presented, where the magnetic field requirements, the significant magnetic coupling between the solenoids, the curved muon transport geometry and the large beam induced energy deposition into the superconducting coils pose significant challenges to the magnetic, mechanical and thermal design of this system.

TL;DR: In this article, the expected sensitivity to the μ − N→e − + N branching fraction relative to muon capture is R μe −17 at 90% confidence level, roughly 3-4 orders of magnitude lower than current limits.
