The weirdest subatomic particles require enormous equipment to study
Of all the elementary particles in the universe, neutrinos may be the strangest. Sometimes known as “ghost particles,” these mysterious little packets of energy have no electrical charge, have almost no mass and come in at least three distinct varieties. New research is bringing science closer than ever to understanding the nature of neutrinos, from their size to their fundamental properties.
Theoretical physicists still know remarkably little about neutrinos, despite the fact that they have been aware of their existence for nearly a century. In 1930 renowned physicist Wolfgang Pauli was puzzling over a seemingly impossible conundrum. Over multiple experiments, Pauli’s contemporaries had noticed an accounting error when observing beta decay, a process by which certain radioactive atoms break down.
But in 2015 Takaaki Kajita of the University of Tokyo and Arthur McDonald of Queen’s University in Ontario won the Nobel Prize in Physics for research that proved the particles do actually have mass—though it did not reveal how much. In the mid-2000s the Mainz Neutrino Mass Experiment in Germany had set the upper limit of a neutrino’s mass at 2.3 electron volts. And in early 2022 data from the Karlsruhe Tritium Neutrino Experiment in Germany .
Researchers are currently developing new experiments to further our understanding of neutrinos. One of them, dubbed the Deep Underground Neutrino Experiment, or DUNE, aims to understand another mysterious property of neutrinos: how they oscillate, or change type.
