Abstract
DUNE is a future on-axis long-baseline neutrino oscillation experiment under construction in South Dakota, USA. Preceding it are two prototype experiments currently located at CERN - ProtoDUNE-SP and ProtoDUNE-DP. During the fina months of the LHC 2018 running period, a mixed particle beam was provided to the ProtoDUNE-SP detector, where over 4million beam trigger events were recorded. This data will be used to benchmark many aspects of the detector technology, and the results from it are vital to the success of DUNE’s full scale detector.
Analysis of electron induced electromagnetic showers using ProtoDUNE-SP’s2018 beam data and ‘Production 2’ Monte Carlo has been performed. A number of modification to existing reconstructed variables have been suggested to better meet the requirements of their intended use cases. Energy estimations have been shown to provide resolutions within the expected range of a calorimeter, and dE/dx measurements align with expected values also.
The Pandora reconstruction software has been applied to the nucleon decay search through the p - K+V¯ channel, and a BDT has been implemented with a sensitivity of 8.0 × 1033 years.
