The vanishing neutrinos that could upend fundamental physics

The search for exotic ‘Majorana’ particles that could solve a big antimatter mystery is ramping up around the world.
By
  1. Davide Castelvecchi

Italian physicist Ettore Majorana notoriously disappeared in 1938 without leaving a trace. His favourite elementary particles, neutrinos, might be capable of a similar vanishing act. Several new or upgraded experiments around the world are racing to show that an extremely rare kind of nuclear decay that normally produces two neutrinos might occasionally yield none.
