Our Current Theory: The Standard Model
Baryons (including protons, neutrons, and mesons) are made up of quarks bound together by gluons
Quarks and Leptons come in pairs (e.g., an electron and its neutrino ne)
- Fermions: Quarks, Leptons (e.g. electrons)
- Bosons: Force Carriers (e.g. photons)
- Only the quarks feel the effects of the strong nuclear force. Quarks and leptons feel the weak nuclear force. All particles that have electric charge feel the electromagnetic force.
