GLoBES Simulations of DUNE Detectors

DUNE (the Deep Underground Neutrino Experiment) measures neutrino oscillations by comparing a near detector close to the beam source with a far detector 1,300 km away in South Dakota. What the experiment can ultimately say about oscillation parameters — mass splittings, mixing angles, CP violation in the lepton sector — depends heavily on detector configuration choices made long before any data is taken.

GLoBES (the General Long Baseline Experiment Simulator) is the standard tool the neutrino community uses to answer "what would we actually be able to measure" questions like this ahead of time: it takes a beam spectrum, detector response, and systematic-error model, and propagates them through to statistical sensitivity on the oscillation parameters.

This project used GLoBES to compare sensitivity outcomes across candidate DUNE far-detector configurations, quantifying the trade-offs between design choices in terms of what they'd cost or gain in oscillation-measurement precision.
