Description
Exchanging a virtual $\tau$ between a $\mu\to \tau$ and a $\tau\to e$ flavour changing vertex results in $\mu\to e$. This talk will discuss the sensitivity of $\mu\to e$ observables to products of $\mu\to \tau \times \tau \to e$ interactions in the Standard Model Effective Field Theory and in a $Z'$ model. We will show that the exceptional sensitivity of upcoming $\mu\to e$ experiments could allow to probe parameter space beyond the reach of upcoming $\tau\to l$ searches, providing complementary information on $\tau$ flavour change.
