Fundamental Matter Particles

Dividing things into smaller and smaller pieces

Matter Particles

There are two kinds of fundamental constituents of matter, leptons and quarks, which have shown no structure yet. The leptons and quarks have three generations which have the same properties except for the masses.

There are mysterious symmetries such as the doublet structure and the correspondence between quarks and leptons within each generation. It is believed that there must be some deep reason to this.
