LBL: STAR Discovers the Strangest Antimatter Yet

STAR Discovers the Strangest Antimatter Yet
Lawrence Berkeley National Laboratory - 2010 March 04
The strangest form of antimatter ever seen has been discovered by the STAR experiment at the Relativistic Heavy Ion Collider (RHIC), at DOE’s Brookhaven National Laboratory in New York. The new particle goes by the jawbreaking name “anti-hyper-triton.”

Translated, that means a nucleus of antihydrogen containing one antiproton and one antineutron – plus one heavy relative of the antineutron, an antilambda hyperon. It’s that massive antilambda that makes the newly discovered antinucleus “hyper.”

PhysOrg: researchers create new matter -- and new questions

From two-trillion-degree heat, researchers create new matter -- and new questions
PhysOrg General Physics - 2010 March 04
A worldwide team of researchers have for the first time created a particle that is believed to have been in existence immediately after the creation of the universe - the so-called "Big Bang" - and it could lead to new questions and answers about some of the basic laws of physics because in essence, it creates a new form of matter.
