Document Summary
Elementary particles are the simplest building blocks of matter. All elementary particles are either quarks or leptons. Bar yons (3 quar k co mbonations ) Every meson has two quarks with some examples are listed above. Every baryon has three quarks with examples listed above such as protons and neutrons. Any particle made up of quarks is called a hadron. Hadrons are the particles that are commonly used at places like cern in geneva and fermilab in. There are six different types of quarks and antiquarks. Different combinations of these quarks make different particles: Electron-positron pair production (for photons of energy > 1. 022 mev) There are six types of leptons (three pairs). The bottom leptons in each pair (positron, muon-, tau-) are relabeled as neutrinos. Leptons are continuously being created and destroyed (some more than others) using two methods: It is not a literal spin, but an amount of intrinsic angular momentum that can help identify a particle.
