Measurement of $\hat{I}{½}_{\hat{I}}¼$-induced charged-current neutral pion production cross sections on mineral oil at $E_{\hat{I}}½\in 0.5-2.0$ GeV

Abstract

Using a custom 3 Čerenkov-ring fitter, we report cross sections for $\hat{I}{½}_{\hat{I}}¼$-induced charged-current single $\ddot{I}{€}^0$ production on mineral oil (\chtwo) from a sample of 5810 candidate events with 57% signal purity over an energy range of $0.5-2.0$GeV. This includes measurements of the absolute total cross section as a function of neutrino energy, and flux-averaged differential cross sections measured in terms of $Q^2$, $\hat{I}{¼}^{-}$ kinematics, and $\ddot{I}{€}^0$ kinematics. The sample yields a flux-averaged total cross section of $(9.2\pm 0.3_{stat.}\pm 1.5_{syst.})\times 10^{-39}$cm${}^2$/CH${}_2$ at mean neutrino energy of 0.965GeV.
