MicroBooNE

A new MicroBooNE paper on arXiv! This one investigates what liquid argon is capable of at low energies: the MeV scale. In this paper, we show that we can measure the energies of 1.6 MeV electron-positron pairs with a resolution of about 7.5%. This is the first ever measurement of MeV-scale energy resolution in a neutrino liquid-argon time projection chamber, and bodes well for the characterisation of low-energy neutrinos from the sun and from supernovae.

We're delighted to welcome Mark Ross-Lonergan as co-spokesperson of MicroBooNE! Mark, from Columbia University, takes over from Matt Toups of Fermi National Accelerator Laboratory, who did an outstanding job leading the collaboration.

MicroBooNE has already made a remarkable impact, from searches for sterile neutrinos and beyond-Standard-Model physics, to precision measurements of neutrino interactions and novel liquid-argon detector techniques. But the science programme ahead of us is every bit as exciting, and we can't wait to share what's coming.

Welcome, Mark! 🎉

Mark Ross‑Lonergan elected co-spokesperson for MicroBooNE collaboration MicroBooNE, with its large neutrino detector at Fermilab, has wrapped up the data-collecting phase and will continue to conduct analysis under fresh leadership.

A new MicroBooNE paper! A new measurement of the electron-neutrino charged current cross section on argon, for interactions without any final-state pions. There are relatively few such measurements for electron neutrinos, so this is an important input for interaction models. https://arxiv.org/abs/2603.13593
