Description
The Deep Underground Neutrino Experiment (DUNE) is a long baseline oscillation experiment that will test the three-flavor neutrino paradigm and measure all of its parameters, including mass ordering and the CP-violating phase, as part of a broad physics program. DUNE will utilize a powerful wideband spectrum neutrino beam, four 10 kt Liquid Argon Time Projection Chamber (LArTPC) Far Detector (FD) modules, and a Near Detector (ND) complex located close to the source. The DUNE ND, which includes a LArTPC, will allow for characterization of the beam and to build predictions for the oscillated spectra at the FD. Its proximity to the beam will enable high-statistics, high precision measurements of neutrino interactions. Event reconstruction is a crucial step that enables physics analysis of the high-resolution LArTPC data. This poster describes tools developed for the high-level characterization of electromagnetic showers in the liquid argon ND reconstructed with Pandora, an advanced multi-algorithm pattern recognition software, and the first application of these tools to physics analysis studies.
