Following hot on the heels of the observation of antihyperhydrogen-4 (a bound state of an antiproton, two antineutrons and an antilambda) earlier this year by the STAR collaboration at the ...

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 ...

This incredibly exotic form of matter contains two antiprotons, an antineutron, and an unstable particle called an antilambda comprised of subatomic quarks.

Physicists with the ALICE Collaboration at CERN’s Large Hadron Collider (LHC) have seen the first ever evidence of antihyperhelium-4, which is composed of two antiprotons, an antineutron and an ...

Heavy ion collisions at the Large Hadron Collider generate conditions conducive to the formation of hypernuclei and their antimatter versions, providing insight into the early universe. Recent ...

Antihyperhelium-4: World’s largest atom smasher detects heaviest antimatter to date Antihyperhelium-4 consists of two antiprotons, an antineutron and an antilambda particle. Updated: Dec 11 ...

In the Large Hadron Collider at CERN, collisions occur where, for a fraction of a second, the conditions that existed right after the Big Bang happen once more. In the deluge of particles that ...

The ALICE collaboration reported the 1st ever evidence of antihyperhelium-4, consisting two antiprotons, an antineutron, and an antilambda.

The ALICE collaboration at the LHC has provided the first evidence of antihyperhelium-4, the heaviest antimatter hypernucleus detected to date. This new antimatter nucleus consists of two antiprotons, ...
