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.

NEUTRINOS
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
property that allows the neutrino to interact.
The white area
represents the weak charge of the neutrino. This charge - entirely
separate from electric charge - gives rise to the Weak Nuclear Force.
This force allows the neutrino to interact - but only very weakly and
its typical range is much smaller than the diameter of a proton.
Neutrinos
are produced when a down quark decays into an up quark, and an
electron. Conservation laws require that a tiny neutral particle is
created in beta decay and that particle is the neutrino (technically an
anti-neutrino)
Because the neutrino only interacts through the
weak force (and negligible gravity) it almost never interacts with other
particles on its own. Millions of neutrinos stream through your body
every second totally unnoticed and unnoticeable.
