Cryogenic mastery aids bid to spot elusive matter creation

A cubic metre of tellurium held at cryogenic temperatures over many years has enabled a search for matter created in a rare nuclear process. The feat bodes well for stabilizing other complex systems at low temperatures.

Astrophysical observations reveal that the Universe is made almost entirely of matter, with nearly no antimatter in sight. However, laboratory and particle-collider experiments have so far observed the creation of matter and antimatter in equal parts. Big Bang theories that aim to explain the cosmic matter imbalance predict that matter could be generated without antimatter in a ‘little bang’, during an ultra-rare nuclear process called neutrinoless double-β decay. In a paper in Nature, the CUORE Collaboration¹ reports the most sensitive search yet for this type of decay using isotopes of tellurium. The decay was not observed, but the engineering feat was remarkable — requiring the stable operation of more than a tonne of experimental apparatus, at cryogenic temperatures close to 10 millikelvin, over several years.
