The Complex Structure of Gluons
The gluon structure of the QCD vacuum is very rich and complex.
The short-lived instantons, displayed here by their localized energy, act to bind low-energy quarks to their locations.
Quarks are thought to hop from instanton to instanton as they fluctuate in and out of the vacuum.
It is this interaction between quarks and gluons that gives rise to the mass of protons and neutrons and thus most of the world around us.
