Classroom Aid - Weak Force W and Z Bosons

Music free version -
Wiki page

In this 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 electric 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 Chromo Dynamics – 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 show how the Large Hadron Collider (LHC) at CERN works and how the Higgs particle was discovered.

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 (like Super Symmetry). We end with a description of Planck’s Length (the shortest distance that can exist) and its implications for the next generation of physicists

Thank you SU MUCH for making it clear that the Weak Force is actually a force that pushes and pulls things, just like the other forces. That makes this video almost unique in the internet. Almost all jump immediately to the particle changing aspect of the interaction. I have noticed that many people watching such videos believe that the Weak Force isn't an actual force.

Thank you so much, I’ve been reading different physics forums for days and when I thought I had it figured out a new question would arise. But this covered all my concerns

[neomayer]

This is a phenomenal video. Answered about 8 separate questions I had, which I couldn't find clear answers to ANYWHERE else. 

I was about to accept that maybe I'd never understand the Weak force, but this video filled me right up. Thank you so, so, so much for explaining this so clearly!!!

[GIRGHGH]

Not the best for my sensitive ears but this is the first video I've seen that actually mentions Z bosons as doing anything and W bosons having charge. I appreciate it very much.

My God !
It is hard to understand. But with yr explanation I can get It.
Thanks

Can you please do a video book on dimensions and string theory..

[SeanBunker]

Ok based on photons have zero mass and they have energy if increasing/decreasing energy increases/decreases mass or amplitude or vibration increasing or decreasing vibration is sound and hertz is like the station the sound comes comes on amplitude is volume what happens if you turn the volume up and down when it is light or sound or what do you get if then you change then if you alter vibration at a high speed then how does how would each effect each type of photon and then the vibration

Good job with the disgusting saliva sounds! Are you using a gate or a filter?
