Strong Interaction
|
|
quarks and gluons have charge that's not electric
same mathematics as color, so "color" charge
force between color-charged particles very
strong
holds quarks together to form protons, neutrons,
etc.
carrier particles called gluons
only quarks and gluons have color charge
protons and neutrons are color neutral, as leptons
strong force only acts at really small distances
electric charge
vector: (+ o
-) 3 basic values
3 x 3 color charge matrix:
(9 combinations - 1 constraint)
= 8 basic values
| red | green | blue | |
| anti-red | r r | gr | b r |
| anti-green | r g | g g | b g |
| anti-blue | rb | g b | b b |
Note: Italic letters are anti-particles
