||The Standard Model seeks to describe the fundamental "point-like" particles of Particle Physics and the interactions between them. It has been known for quite some time now that the normal particles such as protons and neutrons, pions kaons etc are not fundamental. The fact that the neutron possesses a magnetic moment is evidence enough that the neutron must be a composite particle and this was known many decades ago. In fact, we now believe that the fundamental particles are the quarks and leptons, which seem to exhibit no evidence for internal structure down to the smallest measurable distances (10~18 m). Table 1 summarises the situation for both composite and fundamental particles. Note that all existing particles can be divided into two camps namely Fermions (which obey the Pauli Exclusion Principle) and Bosons (which don't).
