All elementary particles are either bosons or fermions (depending on their spin). The spin-statistics theorem identifies the resulting quantum statistics that differentiates fermions from bosons. According to this methodology: particles normally associated with matter are fermions, having half-integer spin; they are divided into twelve flavors. Particles associated with fundamental forces are bosons, having integer spin.
Fermions:
Quarks — up, down, charm, strange, top, bottom
Leptons — electron neutrino, electron, muon neutrino, muon, tauon neutrino, tauon
Bosons:
Gauge bosons — gluon, W and Z bosons, photon
Other bosons — Higgs boson, graviton
The Standard Model of particle physics contains 12 flavors of elementary fermions, plus their corresponding antiparticles, as well as elementary bosons that mediate the forces and the still undiscovered Higgs boson. However, the Standard Model is widely considered to be a provisional theory rather than a truly fundamental one, since it is fundamentally incompatible with Einstein's general relativity. There are likely to be hypothetical elementary particles not described by the Standard Model, such as the gra
