Muon Track Reconstruction in the Scintillator Phase of SNO+

Abstract

The large depth of the SNO+ experiment (2070 m, 6010 m.w.e.) means that only a few muons per day pass through the detector. However, their high energy causes muon induced backgrounds which can affect multiple physics analyses. Reconstructing the muon track would allow for improved rejection for these induced backgrounds. Currently there is no muon tracker for the scintillator phase of SNO+. This poster presents a novel method of muon track reconstruction by using the high photon sampling from muons and the assumption that each PMT first registers a hit from a photon that takes the fastest possible path from the muon entry point to the PMT.
