Probing τ flavour change with μ→e observables

Plenary Presentation Monday afternoon

Speaker

Marco Ardu (Univ. Valencia and CNRS, LUPM)

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 $Z^{\prime }$ 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.
