- particles
- are they affected by the strong force?
- yes-Hadrons
- baryons
- heavier than mesons
- protons and neutrons
- not primary matter
- protons (u+u+d)
- 2/3 +2/3 -1/3 =1 electron charge
- anti protons (-u-u-d)
- neutrons (d+d+u)
- -1/3 -1/3 +2/3 +0 electron charge
- anti neutrons (-d-d-u)
- antibaryons
- made of 3 anti quarks
- made of 3 quarks
- if unstable change into a stable proton
- heaver than Leptons
- baryons
- no- Leptons
- electron leptons
- electrons +electron nutrenos
- neutrinos interact very little
- travel almost as fast as light
- neutrinos interact very little
- electrons +electron nutrenos
- lighter than Hadrons
- leptons and antileptons can interact to produce Hardons
- electron leptons
- yes-Hadrons
- are they affected by the strong force?
- charge of -1/3 electron charge
