Strange matter Illustration of how antihyperhelium-4 – a bound state of two antiprotons, an antineutron and an antilambda – is created in lead–lead collisions at CERN. (Courtesy: CERN/ J Ditzel with ...

If an antineutron hits a neutron, both turn into energy. All this action was predicted by theory. The Berkeley scientists, by carefully screening out of the beam all antiprotons and gamma rays, ...

“And for every further antineutron or antiproton you add, you lose another factor of a million,” says Michael Doser, spokesman for CERN’s AEGIS experiment studying the properties of antimatter.

Scientists first predicted the existence of antimatter in 1928, and discovered it in 1932. The first simple antimatter nucleus (an antiproton stuck to an antineutron) was discovered a few decades ...

The antihypertriton – consisting of an antiproton, an antineutron and an antilambda particle – is the heaviest antinucleus yet produced and opens up a new realm of strange antinucluei. It could also ...
