Search for heavy neutral leptons in electron-positron and neutral-pion final states with the MicroBooNE detector

MicroBooNE collaboration, P. Abratenko, O. Alterkait +185

We present the first search for heavy neutral leptons (HNL) decaying into $\nu e^{+}{e}^{-}$ or $\nu {\pi }^0$ final states in a liquid-argon time projection chamber using data collected with the M…
