Figures-of-merit around 0.1 can be reached in principle over a wide range of antiproton energies. In this process antineutrons with Polarisation > 70% emerge. The method is presented for the case of ...

Lab celebrates a year of scientific successes, from creating the biggest bits of antimatter to improving qubits, catalysts, batteries, and more! With one-of-a-kind research facilities leveraged by ...

Following the discovery of antihyperhydrogen-4 (a bound state of an antiproton, two antineutrons, and an antilambda) by the STAR collaboration, the ALICE collaboration at the LHC has now observed the ...

Earlier this year the STAR collaboration at the Relativistic Heavy Ion Collider (RHIC) produced antihyperhydrogen-4 – an antiproton, two antineutrons, and an antilambda – just slightly lighter ...

When cosmic rays break apart atoms several tens of miles above Earth's surface, they also generate particles called antineutrons. Some of "these antineutrons escape the atmosphere and subsequently ...

This extremely (relatively!) heavy discovery contains one antiproton, two antineutrons, and one anti-Lambda hyperon—all of which fly from a violent collision that knocks matter and antimatter ...

Heavy particle Artistic representation of antihyperhydrogen-4, which is an antimatter hypernucleus made of an antiproton, two antineutrons, and an antilambda particle. It has been created by colliding ...

However, this raises another question. Antielectrons, antiprotons and antineutrons should be able to combine to make whole antiatoms, and indeed antiplanets and antigalaxies. What's more ...
