摘要
En 中文
Lepton Flavour Violation (LFV) is New Physics that must occur, but is stringently constrained by experiments searching for mu <-> e flavour change, such as mu -> e gamma, mu -> e (e) over bare or mu -> e conversion. However, in an Effective Field Theory(EFT) parametrisation, there are many more mu <-> e operators than restrictive constraints, so determining operator coefficients from data is a remote dream. It is nonetheless interesting to learn about New Physics from data, so this manuscript introduces observable-vectors in the space of operator coefficients, which identify at any scale the combination of coefficients probed by the observable. These vectors have an overlap greater than or similar to 10(-3) with most of the coefficients, and are used to study whether mu -> e gamma, mu -> e (e) over bare and mu -> e conversion give complementary information about New Physics. The appendix gives updated sensitivities of these processes, (and a subset of tau -> l decays), to operator coefficients at the weak scale in the SMEFT and in the EFT below m(W).
