Chasing Ghost Particles: Is Neutrino Directional Reconstruction Possible with DUNE's LAr-TPC?

This poster presents a study on the detection capabilities of the Deep Underground Neutrino Experiment (DUNE) collaboration's Liquid Argon Time Projection Chamber (Lar-TPC), specifically its potential to reconstruct the directionality of supernova neutrinos. Using the MARLEY simulation software, we modeled neutrino-argon interactions and analyzed the kinematics of final-state particles. Our findings demonstrate that while the total energy and momentum distributions of Fermi and Gamow-Teller transitions are statistically indistinguishable, the composition of the final-state particles provides a clear signature. Gamow-Teller transitions uniquely produce nuclear products (protons and neutrons), offering a novel method for identifying these interactions and potentially reconstructing a neutrino's original direction. Supernova neutrinos provide insights of stellar core-collapse, which allows for deeper understanding of fundamental physics.
