The
Standard Model of particle physics is a theory of three of the four
known fundamental interactions and the elementary particles that take
part in these interactions. These particles make up all visible matter
in the universe.
Every high energy physics experiment carried out
since the mid-20th century has eventually yielded findings consistent
with the Standard Model.
Still, the Standard Model falls short of
being a complete theory of fundamental interactions because it does not
include gravitation, dark matter, or dark energy. It is not quite a
complete description of leptons either, because it does not describe
nonzero neutrino masses, although simple natural extensions do.

ELECTRONS
The
particle itself is a fundamental particle and is too small to be seen
by any imaginable instrument of observation. So we instead represent the
properties that allow the electron to interact. The central small dot
represents the weak charge of the electron. This charge entirely
separate from electric charge gives rise to the Weak Nuclear Force.
This force causes radioactive decay and its typical range is much smaller than the diameter of a proton.
The
larger volume of shifting purple is meant to represent the Electric
Charge of the electron. This charge is the generator of the
Electromagnetic Force which has infinite range although the drop off in
strength is pretty dramatic as we move away from the electron.
The
Electromagnetic Force is how electrons interact with other electrically
charged particles and with magnetic fields. These interactions make the
structure of atoms and molecules possible. This gives rise to almost
all of the complexity that we see around us.
PROTONS
The
Proton is composed of two up quarks and one down quark (as you can see
from the tiny rings of color near the center of each quark.) The overall
charge of the proton is positive and so we have given it a gold shell.
(Note that we can simply add the charges of the individual quarks to get
the charge of the proton).
The red, green, and blue colors of
the quarks represent the color charge which generates the Strong Nuclear
Force that holds them together. It comes in three different charges
represented here by the three colors, and for different colors the force
is attractive.
The mediator of the Strong Force (the particle
that is exchanged in an interaction) is a gluon. We represent gluon
exchange as the occasional wispy strings between the quarks. As you can
see the gluons have color themselves, and each gluon exchange causes the
quarks involved to swap color. Although we show the quark motion inside
the proton as leisurely, they are actually traveling close to the speed
of light.
NEUTRONS
The Neutron is composed of two down
quarks and one up quark (as you can see from the tiny rings of color
near the center of each quark.) The overall charge of the neutron is
neutral and so we have given it a silver shell. (note that we can simply
add the charges of the individual quarks to get the charge of the
neutron. )
The red, green, and blue colors of the quarks
represent the color charge that generates the Strong Nuclear Force that
holds them together. It comes in three charges represented here by the
three colors, and for different colors the force is attractive.
