Washington, March 5 (ANI): An international team of scientists studying high-energy collisions of gold ions at the Relativistic Heavy Ion Collider (RHIC) has published evidence of the most massive antinucleus discovered to date.
The new antinucleus, discovered at RHIC's STAR detector, is a negatively charged state of antimatter containing an antiproton, an antineutron, and an anti-Lambda particle.
It is also the first antinucleus containing an anti-strange quark.
