Exploring Coherent Pion Production at Low Energies with MINER$\nu$A and SciBooNE

This study focuses on measuring coherent pion production at low neutrino energies. Experiments using the SciBar detector in two beams have produced results consistent with no coherent pion production in this energy range. The model employed has shown promise in capturing both resonance and coherent production kinematics, particularly in the analysis of neutral pions. MINER$<br>u$A's novel nuclear targets allow for the first A-dependence measurement of coherent pion production across a wide range of nuclear masses. The planned low energy neutrino beam from MINER$<br>u$A is expected to yield around 300 CC coherent pion events with high purity and detection efficiency, providing valuable insights into this phenomenon. Performance metrics include resolutions for energy and angle reconstruction, showcasing the capability to cleanly identify and study coherent and resonance events involving pions.
