The Standard
Model
By: Dorca Lee
Standard Model
Current theory of fundamental particles,
and, how they interact.
Ingredient Particles
6 leptons
6 quarks
Force carriers
NOTE: Also includes respective
antiparticles.

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