abstract = {We present a measurement of η 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
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 Δð1232Þ. We
measure a flux-integrated cross section for neutrino-induced η production on argon of 3.22   0.84ðstatÞ  
0.86ðsystÞ 10−41 cm2=nucleon. By demonstrating the successful reconstruction of the two photons
resulting from η production, this analysis enables a novel calibration technique for electromagnetic showers
in GeV accelerator neutrino experiments.},
