Search for the production of Higgs-portal scalar bosons in the NuMI beam using the MicroBooNE detector
MicroBooNE collaboration, P. Abratenko, D. Andrade Aldana +178
We present the strongest experimental limits to date on the mixing angle, , with which a new scalar particle, , mixes with the Higgs field in the mass range $110\text{ MeV}<…

Demonstration of new MeV-scale capabilities in large neutrino LArTPCs using ambient radiogenic and cosmogenic activity in MicroBooNE
MicroBooNE collaboration, P. Abratenko, O. Alterkait +184
Large neutrino liquid argon time projection chamber (LArTPC) experiments can broaden their physics reach by reconstructing and interpreting MeV-scale energy depositions, or blips,…
