Search for $K^+$ decays to a lepton and invisible particles

Searches for heavy neutral leptons $N$ in the $K^+\to e^+N$ and $K^+\to \mu^+N$ decay channels using the dataset collected by the NA62 experiment at CERN between 2016-2018 are presented. Upper limits on the corresponding mixing matrix elements are reported at the level of $\mathcal{O}(10^{-9})$ and...
