Description
Lorentz and CPT invariance are among the most fundamental physical symmetries. Progress in recent years has led to stringent constraints on several coefficients parametrizing Lorentz and CPT violation coupled to the fields of the standard model and general relativity. However, nonrenormalizable operators inducing tree-level lepton-flavor-violating decays remain completely unexamined. In this talk, I discuss the dominant dimension-five operators of this type initiating flavor-changing muon and tau decays and their resulting bounds using existing MEG and BaBar measurements. The outlook for improved constraints in future experiments will also be discussed.
