1Name the two subsections of ParticlesHadrons and Leptons
2Two types of Hadrons?Baryons and Mesons
3Types of LeptonsElectrons, Muons, Electron-neutrino, Muon-neutrino
4Baryon number of baryons, Anti-baryons, mesons and leptons+1, -, 0 and 0
5Qualities that need to be conserved in order for a particle interaction to happenBaryon number, Lepton number, Energy, Momentum and sometimes strangeness
6Which is heavier and which is more unstable: a Kaon or a Pion?Kaons are both heavier and more unstable than Pions. Kaons decay into Pions
7Properties of Neutrinos (mass, charge, force of interaction, types)No/Almost no mass, no electric charge, interact with the weak force only. Types: Electron and Muon neutrinos
8Lepton Electron Number of: Electron Electron Neutrino Muon Muon Neutrino What about their anti-particlese- = +1
ve = +1
u- = 0
vu = 0
Antiparticles are reversed lepton number and charge
9What kind of Hadrons have strangenessKaons
