Higgs boson for dummies!

finally here it comes, here it goes, post about Higgs boson is coming. Lets look what the “god’s particle” is how physicists found it and what it means.


God’s particle

Lets see how Higgs boson was named the god’s particle.

One of the best particle physicists Leon Lederman who found out that there are more types of neutrinos and so on and on. He wrote a book named the “God’s particle”. The book was partially named like this because the publisher did not want it to be named “Damned particle”.

He did this and now all physicists can agree on one thing, they hate this phrase because Higgs boson has nothing to do with God.

While all journalists can agree that “God’s particle” is amazing phrase.

So if you want some physicist to be angry on you, just mention the God particle and he will never forget.

Higgs boson was found 4.7.2012 in Large Hadron Collider.

Higgs field

What is actually more important than Higgs boson, the particle, is the field from which it came, this is the Higgs field. I already talked in last post about fields and how specific vibrations can form particles. Higgs field can do this too and it makes the higgs boson which decay almost immediately and is really hard to detect.

Higgs field is a very different from other fields because other fields can get to 0 energy while Higgs field can not. What is more accurate to say is that non zero value of Higgs field is less energetic than zero so Higgs field does not want to fall on the value of 0.

What does it do?

Well you may have heard about Higgs field giving mass to matter. This is partially true since when particle interacts with Higgs field they are kind of slowed so they do not travel at the speed of light. Some particles interact more than others like some people interact with group of people more than others because they are well known [1].

At one post I wrote about symmetries, check it out if you did not already. There is symmetry in particles. They are all the same.
What? Now this symmetry is broken, this means that there are differences between particles, thanks Higgs field! This is the most important effect of the field with the effect that while it would not change much the mass of protons and neutrons, it would change the mass of electron rapidly if it would not exist. Now the space occupied by particles as electrons is set and such a light particles need to have a lot of space around them. If you would turn off Higgs field completely, things would probably gone exploding a lot since the size of atom would increase as the space around electron needed would get bigger.


[1] This does not mean that all the mass is from Higgs field, most mass of neutron and proton is made up of energy m=E/c^2.
