Analysis of DUNE Simulation Data of Near Detector to Study the Neutral Current Background

The analyses on charged current and neutral current interactions based on a full simulation, reconstruction, and event selection of the near detector of the Deep Under- ground Neutrino Experiment (DUNE) are carried out. The neutrino beam mode and antineutrino beam mode are included. DUNE will be able to classify the CC and NC interactions. The determination of NC background in DUNE near detector is needed in order to observe charge-parity (CP) violation in the neutrino sector and resolve the neutrino mass hierarchy. Exact determination and reduction on NC background will allow precise measurements of parameters, namely mixing angles and a CP-violating phase which govern long-baseline neutrino oscillation.
