Gluon

Gauge boson mediating strong force between quarks.

Core Principles & Analysis

• First observed directly in three-jet events at DESY's PETRA collider in 1979.
• Comes in eight color states and carries color charge, so gluons interact with each other.
• Gluon self-interaction confines quarks, which is why no free quark has ever been observed.
