Poster Neutrino interactions Poster


Liquid argon time projection chambers (LArTPCs) are well suited for use as neutrino detectors due to their exceptional calorimetric and position resolution capabilities, and in particular, their ability to distinguish between electrons and photons. The MicroBooNE experiment uses the LArTPC technology to investigate an anomalous excess of low-energy events reported by the MiniBooNE experiment. The origin of the anomalous events could be photon-like or electron-like in nature.
To test the photon-like hypothesis, MicroBooNE is searching for single-photon events. However, the neutral-current (NC) π0 production process presents a real challenge in this task, since it is more common than single-photon events and has 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.
