Abstract

The cross section of neutrino-induced neutral-current coherent π0\pi^0 production on a carbon-dominated target is measured in the NOvA near detector. This measurement uses a narrow-band neutrino beam with the average neutrino energy of 2.7\,GeV, xwhich is of interest to the ongoing and future long-baseline neutrino oscillation experiments. The measured, flux-averaged cross section is σ=14.0±0.9\sigma = 14.0\pm0.9\,(stat.)±2.1\pm2.1\,(syst.)×10−40\times 10^{-40} cm2/\text{cm}^2/nucleus, consistent with model prediction. This result is the most precise measurement of neutral-current coherent π0\pi^0 production in the few-GeV neutrino energy region.
