DUNE and the Neutrino Mass Hierarchy Problem

By: Hannah Pell Image credit: ProtoDUNE / CERN. Why does matter exist in the universe? Can we find evidence of proton decay, supporting Einstein's dream of unified forces? These questions, among a host of others, are very much open for debate within high-energy physics, and one particle has the potential to help answer all of them: the neutrino. If only we could find out how much they weigh. This is the crux of the longstanding neutrino mass hierarchy problem that the Deep Underground Neutrino E...
