Force Carriers

• Strong force mediated by gluons
• Weak and electromagnetic Forces are mediated by
  W, and Z gauge bosons.
• Gravity is mediated by graviton.

Color Charge

• Quarks and gluons are color-charged particles
• When two quarks are close to one another, they
  exchange gluons and create a very strong color
  force field that binds the quarks together.

11
Color Charge

• A quark may have 1 of 3 possible color charges
  an antiquark may have 1 of the 3 complementary
  color charges and a gluon may have 1 of 8 kinds
  of color charge.
• All observed particles are color-neutral objects

12
Conservation Laws

• Conservation of mass and energy
• Conservation of angular momentum
• Conservation of charge
• Color Neutrality
• Conservation of isospin, charmness, strangeness,
  topness, and bottomness
