Progress towards Charged Current Coherent Pion Production Cross-Section measurement at MicroBooNE

We present progress towards the measurement of charged current (CC) coherent pion production cross-section on argon at low energy using the MicroBooNE liquid argon time projection chamber (LArTPC), with data collected during MicroBooNE’s first physics run. Coherent pion production, characterized by a neutrino interacting with an entire nucleus without breaking it apart, results in a forward-going muon, pion, and a low-momentum recoil nucleus. By leveraging an improved understanding of particle identification and background parameterization, we aim to achieve a new level of sensitivity to coherent interactions at low neutrino energy. The outcome of this analysis will contribute to the ongoing efforts to model neutrino-nucleus interactions accurately in neutrino oscillation studies and beyond the Standard Model searches.
