Summary
In this talk, we discuss the prospects for constraining lepton flavour violation (LFV) physics from tau decays using a general effective field
theory approach. We show that correlations among decay rates and differential distributions in different tau decay channels can provide a basic handle to unravel the origin of LFV in these processes. As an illustration, we consider a Higgs-like boson with LFV and highlight the special role played by
$\tau \to \ell \pi\pi$ decays, which offer a direct connection to the relevant process at LHC, $pp (gg) \to h \to \ell \mu$. Recent developments in the determination of the hadronic form factors needed for this analysis are discussed.
