Scientists Discover Evidence of a New Type of Matter: the Tetraquark

The recent identification of a long-theorized particle provides strong evidence of a new form of matter.

Scientists working on the Large Hadron Collider, the most powerful particle collider in the world, verified the existence of a particle called Z(4430) last week, according to New Scientist. Previously, physicists had reasoned that the particle could exist but had yet to observe it.

Discovery of any new particle is an important step for scientists, but Z(4430) is viewed with particular importance — it is evidence of a new type of matter called a tetraquark. Read more...
