High-resolution MicroBooNE detector provides new details in neutrino-argon interaction measurement

A neutrino candidate event selected by this analysis is shown as a bird’s-eye view of the MicroBooNE detector. In this view, neutrinos arrive from the left. The five prongs show five particles that have been produced by a neutrino interaction with an argon atom. The longest prong is the candidate muon, going backwards with respect to the neutrino direction.

The most recent physics result from the MicroBooNE experiment provides one of the very first rigorous tests of our understanding of neutrino interactions with argon. The paper, published in Physical Review Letters, presents the first ever measurement of neutrino interactions on argon as a function of the momentum and angle of the muon, a particle produced in the interaction (technically called a “double-differential cross section measurement”).

The inside of the ANNIE detector looks like a series of carefully placed Jell-O domes, or perhaps a jeweled Fabergé egg. Its walls are dotted by 137 sensors for detecting packets of light and embrace 26 tons of gadolinium-doped water.
