Neutrino-induced charged-current coherent pion production is an important channel for the study of neutrino-nucleus interactions. It is both a dangerous background for $\nu_{e}$ oscillation experiments, and a critical component required for precise understanding of neutrino-nucleus pion production in general.
This work performed a search for $\nu_{\mu}$-induced charged-current (CC) coherent pion production on argon in MicroBooNE from Fermilab's Booster Neutrino Beamline (BNB), which produces $\nu_{\mu}$ with a mean energy of 0.823 GeV. A flux-integrated cross section measurement was made for this channel, and was found to be: $\sigma(\nu_{\mu} + Ar \rightarrow \mu^{-} + \pi^{+} + Ar) = 1.12 \pm 0.253 \textrm{(stat.)} \pm 0.728 \textrm{(syst.)}\times 10^{-39} \textrm{cm}^{2}$.
