Neutral Current Event Threshold in SBND

The Short-Baseline Near Detector (SBND) is one of three detectors located at Fermilab for use in the Short-Baseline Neutrino (SBN) program. One goal of SBND is to use Liquid Argon Time Projection Chamber (LArTPC) technology to understand neutrino interactions. The photon detection system (PDS) of the experiment consists primarily of 120 cryogenic photomultiplier tubes (PMTs), 192 X-ARAPUCAs, which work together with the LArTPC wire grids to identify interaction tracks. Scintillation light produced within the fiducial volume is used to find a correlation with the final state particles from a neutrino interaction. With minimal energy deposition and the absence of charged lepton production, identifying neutral current (NC) events remains a difficult task. In this talk, we investigate a set of kinematic cuts that minimize external noise while ensuring high identification efficiency for NC events. Further analysis using a weighted sum of light intensity (centroid) to obtain approximate interaction vertices of events within the LArTPC.
