Description
MUonE is a proposed experiment designed to measure the hadronic vacuum polarization contribution to muon $g-2$ through elastic $\mu−e$ scattering. As such it employs an extremely high-resolution tracking apparatus. We point out that this makes MUonE also a very promising experiment to search for displaced vertices from light, weakly-interacting new particles. We demonstrate its potential by showing how it has excellent sensitivity to dark photons in the mass range $10~\mathrm{MeV} \leq m_{A^\prime} \leq 100~\mathrm{MeV}$ and kinetic mixing parameter $10^{-5} \leq \epsilon e \leq 10^{-3}$, through the process $\mu^- e^- \rightarrow \mu^- e^- A^\prime$ followed by $A^\prime \rightarrow e^+ e^-$.
