Deep learning based LArTPC event reconstruction and nonmagnetic muon sign determination in the ICARUS detector
Abstract/Contents
- Abstract
- The Liquid Argon Time Projection Chamber (LArTPC) is a state-of-the-art particle imaging detector technology pioneered at the kiloton scale by the ICARUS detector, now at Fermilab. It will be widely used in accelerator-based oscillation experiments for precision measurements of neutrino oscillation parameters. This thesis demonstrates a novel end-to-end, deep-learning-based data reconstruction chain for LArTPC. This approach can scale up to large existing and upcoming LArTPC neutrino detectors such as ICARUS and DUNE with sparse convolution techniques. We apply it to an electron neutrino selection on ICARUS simulation, which shows promise for a future low-energy excess search. This work further presents two methods for nonmagnetic muon sign determination in ICARUS: comparing the muon decay electron energy spectrum with bound muon decay-in-orbit numerical predictions, and fitting the muon decay time distribution. ICARUS cosmic ray data analysis yields a muon to antimuon ratio of 0.69 +/- 0.12 in agreement with previous measurements. Such methods for statistical separation between muon and antimuon, when applied to a muon neutrino/antineutrino beam, are expected to improve the sensitivity of ICARUS and forthcoming LArTPC experiments to CP-violation, neutrino mass ordering, and neutrino oscillation measurements.
