Description
High-energy astrophysical neutrinos provide a unique messenger for studying the origin of cosmic rays, making precise direction reconstruction a key task for neutrino telescopes. However, underwater neutrino detectors operate in optical backgrounds induced by PMT dark noise and radioactive decays, which challenge hit selection and track reconstruction, especially for the early-stage TRIDENT Phase-I detector. In this work, we develop filtering and direction reconstruction methods for track-like events using the multi-PMT optical modules in TRIDENT Phase-I, including noise suppression and likelihood-based reconstruction with PMT orientation information. This study provides a basis for robust track reconstruction in next-generation deep-sea neutrino telescopes.
