Neutral Current Pion Production Measurement in MicroBooNE

Liquid Argon Time Projection Chambers (LArTPCs) are the current and future detectors employed in studying neutrinos from a beam. Their importance is based on their exceptional calorimetric and position resolution capabilities. In particular, their ability to distinguish between electrons and photons is an advantageous aspect compared to other technologies and a crucial one for neutrino oscillation experiments. The MicroBooNE experiment uses the LArTPC technology to investigate the MiniBooNE low-energy excess, which could also be photon-like in nature. To test this hypothesis, MicroBooNE is searching for single-photon events. However, the NC π⁰ production process presents a real challenge in this task, being more common and having a similar topology. This talk presents a method to improve the current NC π⁰ event selection in MicroBooNE using the Wire-Cell paradigm, as a way to constrain the systematic uncertainty in the single-photon search.
