Behold the pentaquark

Physicists have discovered a new class of subatomic particle that will provide unexpected insights into the fundamental building blocks of matter.
...

The new particle is the so-called pentaquark - five quarks in formation. Until now, physicists had only seen quarks packed into two- or three-quark combinations
...

The discovery of the pentaquark, also known as a new exotic baryon state, should have far-reaching consequences for our theory of particle interactions that attempt to explain the structure of matter.
