In our final segment, we cover the Higgs Boson starting with force fields and their particles.
First
we cover Quantum Electrodynamics - QED. We note that a disturbance in
the field can create a particle – the photon. We show how the virtual
photon mediates the electromagnetic force with virtual photons that are
actually not particles. We also introduce coupling constants and Feynman
Diagrams. We then extend this ‘force particle from a force field’
concept to include a matter particle from a matter field. In
electromagnetic quantum field theory, this is the electron.
Next
we cover Quantum Chromodynamics – QCD. We show how the electromagnetic
force is used as the model for the strong nuclear force that holds
quarks together in protons and neutrons and holds protons and neutrons
together in the atomic nucleus. We introduce color charge, gluons,
virtual gluons, quark containment, and pion exchange between nucleons
(the residual strong force). We also highlight the origin of mass for
the proton. We then fill out the Standard Model of particle physics with
the weak nuclear force and its force particles - the W and Z bosons.
Using Beta Decay, we show how this force can change the actual particle
in an interaction, not just accelerate it.
Next we discuss spin
oscillation as the origin of mass for elementary particles that lead to
the Higgs Field and the Higgs Mechanism, and, as with all other fields, a
disturbance in the Higgs Filed should create a particle – the Higgs
boson.
We’ll conclude with a brief look at what the standard
model doesn’t cover (like gravity) and some of the theories in
development that may very well take physics to the next level. We end
with a description of Planck’s Length and its implications for the next
generation of physicists.
