Abstract
We report the first measurement of the flux-integrated cross section of $\nu_{\mu}$ charged-current single $\pi^{0}$ production on argon. This measurement is performed with the MicroBooNE detector, an 85 ton active mass liquid argon time projection chamber exposed to the Booster Neutrino Beam at Fermilab. This result on argon is compared to past measurements on lighter nuclei to investigate the scaling assumptions used in models of the production and transport of pions in neutrino-nucleus scattering. The techniques used are an important demonstration of the successful reconstruction and analysis of neutrino interactions producing electromagnetic final states using a liquid argon time projection chamber operating at the earth's surface.
Highlights
Neutral pion (π0) production in neutrino interactions can create backgrounds that limit the sensitivity of neutrino νμ → νe oscillation searches, such as those being pursued by DUNE [1,2,3] and the SBN Program [4]

This background comes from photons originating from neutral current (NC) production of π0 → γγ decays that can mimic the topology of an electron originating from a νe chargedcurrent (CC) interaction
Summary
Neutral pion (π0) production in neutrino interactions can create backgrounds that limit the sensitivity of neutrino νμ → νe oscillation searches, such as those being pursued by DUNE [1,2,3] and the SBN Program [4]. This background comes from photons originating from neutral current (NC) production of π0 → γγ decays that can mimic the topology of an electron originating from a νe chargedcurrent (CC) interaction. This article reports the first measurement of νμ CC single π0 production on argon using an inclusive final-state topology of at least one photon coming from a π0 decay in addition to a muon, both exiting the target nucleus
