Abstract

We present a measurement of η\eta production from neutrino interactions on argon with the MicroBooNE detector. The modeling of resonant neutrino interactions on argon is a critical aspect of the neutrino oscillation physics program being carried out by the DUNE and Short Baseline Neutrino programs. η\eta production in neutrino interactions provides a powerful new probe of resonant interactions, complementary to pion channels, and is particularly suited to the study of higher-order resonances beyond the Δ(1232)\Delta(1232). We measure a flux-integrated cross section for neutrino-induced η\eta production on argon of 3.22±0.84  (stat.)±0.86  (syst.)3.22 \pm 0.84 \; \textrm{(stat.)} \pm 0.86 \; \textrm{(syst.)}10−41cm210^{-41}{\textrm{cm}}^{2}/nucleon. By demonstrating the successful reconstruction of the two photons resulting from η\eta production, this analysis enables a novel calibration technique for electromagnetic showers in GeV accelerator neutrino experiments.
