Matter and Antimatter

Matter and Antimatter

1. Hadrons

   • Baryon
     • Interact - Strong and EM
     • 3 Quarks
     • eg. Proton, Antiproton, Neutron and Antineutron
       • Antineutron: Anti(udd)
       • Antiproton: Anti(uud)
       • Proton: uud
       • Neutron: udd
   • Mesons
     • Decay - Weak
     • 2 Quarks
       • Quark and Antiquark pair
     • eg. Kaon, Pion
       • Kaon: u,Anti(s)
         • +: u, Anti(s)
         • -: Anti(u),s
         • o: d, Anti(s)
       • Pion:
         • +: u, anti(d)
         • -: anti(u), d
         • 0: u, anti(u)

2. Leptons

   • Interact - Weak and EM
   • eg. Electron, Positron, Muon, Antimuon, Tau, Antitau, Neutrino, Antinewtrino
     • Electron: Do not contain quarks
     • Positron: Do not contain quarks
   • 0 Quarks

3. Add Quark compositions and then Print off
