Search for $\pi^0$ decays to invisible particles

The NA62 experiment at the CERN SPS reports a study of a sample of $4 \times 10^9$ tagged $\pi^0$ mesons from $K^+ \to \pi^+ \pi^0 (\gamma)$, searching for the decay of the $\pi^0$ to invisible particles. No signal is observed in excess of the expected background fluctuations. An upper limit of $4...
