    The smallest particle that I am aware of is the quark. The quark is the basic building block of hadrons. There are two types of hadrons: baryons (three quarks) and mesons (one quark, one antiquark). Protons and the neutrons are stable baryons.

    There are also leptons, a family of elementary particles that include electrons, muons, tauons, and neutrinos. Neutrinos were originally believed to have zero mass, but they have been found to have a very tiny mass, smaller than any subatomic particle.

    Calling someone a 'hadron head' would be considered an insult among physicists.
