Those leptons had it their own way for far too long.

They are a major constituent of matter, along with leptons.

But were quarks and leptons the end of the story?

In any case the number of leptons would change.

Leptons are a class of particles that do not interact strongly with matter.

The 3 types of neutrinos are named after the previous three leptons.

Leptons are a class of fundamental particles that includes the electron.

The third contained only the 1 lepton, 2, 5, 40 and 60 lepta.

Electrons (the other major component of the atom) are leptons.

A 1 lepton value was printed but never issued.

The world is made up of quarks and leptons!

What is the true nature of quarks and leptons?

Of the six leptons, three have electrical charge and three do not.

The electron belongs to a group of fermions called Leptons.

The main difference between quarks or leptons with the same charge is in how much they weigh.

Additionally, there are six different types of what are known as leptons.

One may ask where do the large lepton mixings come from?

An experimental, unstable version called Lepton had the 2.4 kernel.

The tau is a heavier cousin of the electron, another lepton.

Like the electron, the neutrino is classed as a lepton.

Of course, now we offload old memories into lepton matrices.

There's a guy who ought to be lepton!

In biblical times a mite or lepton was a small coin of almost no worth.

For three generations of leptons, the matrix can be written as:

The lepton is either an electron or a muon.
