In the
Standard Model of
particle physics,
matter are constituted by 12
particle types and their
antiparticles. Matter particules are divided in two classes:
quarks and
leptons.
All other particles, like
protons or
neutrons are made of
quarks, hence the name
fundamental particles.
In addition, gluons, photons, W and Z bosons, the force carrier particles for, respectively, the strong, electromagnetic and weak interactions, are also considered as fundamental particles.
