Optimizing Layouts for Next-Generation Cherenkov Neutrino Telescopes

Recent research has focused on optimizing the geometrical layouts of next-generation large-volume Cherenkov neutrino telescopes. The study, titled "Comparison of Geometrical Layouts for Next-Generation Large-volume Cherenkov Neutrino Telescopes," was authored by Tong Zhu, Miaochen Jin, and Carlos A. Argüelles. It was submitted to arXiv on July 26, 2024, and revised on August 23, 2024. The paper explores various configurations of optical modules (OMs) and larger geometrical volumes aimed at enhancing the detection efficiency of high-energy astrophysical neutrinos.

The authors highlight that while existing telescopes generally utilize similar OM layouts, there is a need to investigate alternative configurations to maximize discovery capabilities. Their research evaluates different layouts based on signal event selection efficiency and reconstruction fidelity, employing both a trigger-level linear regression algorithm and an offline Graph Neural Network (GNN) reconstruction method.

The findings suggest that optimizing the layout of these telescopes could significantly improve their ability to detect neutrinos in the multi-TeV energy range and extend their reach to EeV energies. This advancement is crucial for the scientific community, as it could lead to new discoveries in astrophysics and a better understanding of cosmic phenomena.
