Experiments on electrons interacting with atomic nuclei have shown that the models used to measure neutrino oscillations — and thereby possibly to understand the formation of the Universe — are less accurate than we thought.

These experiments are used to study ghostly particles that hold the secrets of the cosmos, but a new study suggests 70% of interactions are badly reconstructed.

Early-career nuclear physicists show that a better understanding of how neutrinos interact with matter is needed to make the most of upcoming experiments.

Neutrinos are detected by observing the particle showers they create when they strike nuclei, but new research using electrons in place of neutrinos shows that the models used to reconstruct the energy of the incoming neutrinos from these showers usually give wrong answers.
