Description
In this talk, I describe how worldwide experimental searches for charged-lepton flavor-changing processes also provide new opportunities for discovering violations of Lorentz and CPT invariance. Model-independent effective interactions describing perturbative Lorentz and CPT violation have been investigated in electromagnetic muon and tau decays, and coherent muon-to-electron conversion in nuclei. Results from the MEG, BaBar, and SINDRUM II experiments have enabled hundreds of first constraints on coefficients parametrizing time-independent signals of Lorentz and CPT violation. Future experiments, including MEG II, COMET, and Mu2e, are projected to increase these constraints by up to two orders of magnitude. I also outline how time-dependent modulations of transition rates, which remain completely unexplored and are uniquely characteristic of Lorentz and CPT violation, can be probed.
