Each circle in the diagram represents a type of subatomic particle in the Standard Model, according to which particles fall into two classes, fermions and bosons. Fermions are either leptons or quarks.
Bosons carry particular forces between other particles. Particle types linked directly by a blue line interact by means of the force associated with the boson type; particle types not so linked do not interact.
Photons carry the electromagnetic force; W and Z bosons carry the weak nuclear force; and gluons carry the strong nuclear force. Finally, particles that interact with the still-hypothetical Higgs boson obtain
their mass via this interaction, although even massless particles (such as photons) are subject to gravitational effects via general relativity.
