These days I have been talking about two of the four fundamental forces of nature and, because of this, I speak of particles that make… everything.

Maybe that’s why I want to talk about one, the muon.

When I talk about Fermi and fermiones a long time ago using a very bad joke I commented that the particles were divided into two parts, those that have strength and those that have mass.

Muon is one of the particles that are with which they have “mass”, in fact, is what is called a lepton. A lepton is a fundamental particle that has a spin of 1/2 (positive or negative) but essentially has no color . The important thing about leptons is that, now that I have spoken of strong force, it is this that holds them together.

Returning to the muon, this lepton has spin of 1/2 positive and negative electric charge.

The curious thing about muons is that they fulfill a thing with a very complicated name called CPT symmetry that, under that name, the only thing that indicates is that the particle, when it changes some of its properties makes change to the set of them. That is, if you change your spin and from positive to negative, you will also change the type of particle becoming a bullshit. It is called CPT symmetry because three properties: change C, load P parity and T temporality.

As a fundamental particle, it is base, that is, it is not divisible, it does not contain others. It was discovered in 1937 by Carl Anderson studying the cosmic background radiation and seeing as “there was a particle” that changed its direction When applying an electromagnetic field and that deviated different to the existing and known. This gave him the idea that there was something new there that I call meson, but later, it was called muon.
