| Yet experiments indicated that quarks within protons were only loosely bound together. |
| The resulting theory would be able to describe the behavior of the universe, from quarks and atoms to entire galaxies. |
| This process results in two jets of hadronic particles as the quarks form hadrons. |
| The protons and neutrons in the nucleus are made of elementary particles called quarks. |
| Yet they implied the existence of quarks, which seem to be as real as any other objects that we take seriously. |
| Research into the atom's nucleus has uncovered a variety of subatomic particles, including quarks and gluons. |
