Charged particles, like protons and electrons, can be characterized by the trails of atoms these particles ionize. In contrast, neutrinos and their antiparticle partners almost never ionize atoms, so their interactions have to be pieced together by how they break nuclei apart.

But when the breakup produces a neutron, it can silently carry away a critical piece of information: some of the antineutrino’s energy.
