Description
We perform a simulation of dark-vector production from electromagnetic cascades at SHiP. The cascades are initiated by photons from $\pi^0\rightarrow \gamma \gamma$, and lead to substantial increases in sensitivity for long-lived dark vectors with masses below $\sim 50-300~{\rm MeV}$. The dominant production mode in the regions of new sensitivity is $e^+ e^- \rightarrow V(\gamma)$. New sensitivity projections for dark photons and gauged $L_i-L_j$ models are provided for SHiP and compared to previous literature.
