Neutrino Induced Charged-Current Coherent Pion Production at MicroBooNE

Neutrino induced charged-current coherent (CC-Coh) pion production is a rare neutrino-nucleus interaction channel with a controversial history. The interaction channel has been studied extensively at ~7GeV and higher neutrino energies, and is well modeled at these neutrino energies by the Rein-Sehgal model. Recent experiments (SciBooNE and K2K) both attempted to measure this interaction channel’s cross section at lower neutrino energies (~2.5GeV and below), but did not observe the channel and set upper limits. Recently, the T2K collaboration successfully measured the CC-Coh pion production cross section at comparable low neutrino energies, but found that the Rein-Sehgal model is not satisfactory at these lower neutrino energies. The Micro Booster Neutrino Experiment (MicroBooNE) is a Liquid Argon Time Projection Chamber (LArTPC) that is located in the Booster Neutrino Beamline (BNB) at Fermilab. MicroBooNE is in the unique position to measure the CC-Coh pion production cross section at comparable neutrino energies to the SciBooNE experiment with the largest data sample of neutrino-nucleus interactions on argon in the world. This talk will show progress towards the highest-statistics cross section measurement of CC-Coh pion production on argon at ~1GeV neutrino energies.
