摘要
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 Δ(1232). We
measure a flux-integrated cross section for neutrino-induced η production
on argon of 3.22 ± 0.84 (stat.)± 0.86 (syst.)
10^-41cm^2/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.
