Quark

Quark

1. Up Quark (u)

   • 2/3 charge

2. Down Quark (d)

   • -1/3 charge

3. Strange Quark (s)

   • -1/3 charge
   • called strange because has long lifetime

4. Charm Quark (c)

   • 2/3 charge

5. Top (t)

   • 2/3 charge

6. Bottom (b)

   • -1/3 charge

7. Three Color Change

8. Gluon

   • Carries one of eight color-anticolor charges

9. Hardons

   • Baryons (3 quarks)
     • Neutrons (udd)
       • 1 up quark and 2 down quarks
     • Protons (uud)
       • 2 up quarks and 1 down quark
   • Mesons (1 quark and 1 antiquark)
     • Antipion
       • 1 down quark and 1 up antiquark
     • Pion
       • 1 up quark and 1 down antiquark
         • Note: the direction (up, down) of the quark and anitquark has been switch between Antipion and Pion
     • Kaon
       • Lives longer than most mesons
       • Called "strange" and gave this name to the strange quark, one of its components
