LFV in Meson and Baryon Decays—Theory Overview ^#

summary and outlook of the theory motivations and status of searches for lepton flavour violation (LFV) in meson and baryon (semi-)leptonic decays is provided. The contribution is structured as follows: (i) A short overview of b→ s as well as b→ c data; (ii) general arguments for pursuing LFV in b -hadron decays; (iii) additional arguments for possible LFV signatures in other meson decays, in particular, of kaons. Emphasis is on a presentation accessible to a wider public, describing the underlying motivation and physics arguments with a minimum of equations.
