Quark quartet forms exotic particle
Quarks are important building blocks of matter, usually bound together as pairs or triples. Now some have formed a quartet. Scientists confirmed the existence of a particle made of four quarks stuck together. Such strange stuff may have been more common in the earliest universe, the scientists say.
