Contribution

It introduces a comprehensive analysis of DUNE's sensitivity to multiple supernova neutrino flavor conversion scenarios, combining advanced simulation tools and flux models.

Findings

DUNE can differentiate between slow, fast, and standard flavor conversions.

The experiment can accurately reconstruct neutrino flux parameters.

Distinct signatures allow scenario discrimination.

Abstract

The flavour composition of a future supernova neutrino signal is expected to carry measurable imprints of flavour conversion processes in the dense stellar medium. In this work, we analyse the sensitivity of the upcoming Deep Underground Neutrino Experiment (DUNE) to three phenomenologically distinct effects: slow energy-dependent collective oscillations, fast energy-independent collective oscillations, and standard MSW conversions. By integrating GLoBES and MultiNest and using benchmark neutrino fluxes at emission, we assess the potential of DUNE to extract the underlying flux parameters and discriminate among conversion scenarios.
