  2. Structure • Historical introduction • Definition • Particle classification • Fermions • Quarks • Leptons • Gauge bosons, Higgs • Summary • Sources TU Dresden Particles of the Standard Model Sophie Koßagk

  3. Historical introduction • What is the World Made of? Fig.: [1] Fig. : [2] TU Dresden Particles of the Standard Model Sophie Koßagk

  4. Historical introduction • Pion • quantum electrodynamics (QED) • W+, W- Boson • Neutrino • Positron, Neutron • Muon TU Dresden Particles of the Standard Model Sophie Koßagk

  5. Historical introduction • idea of Quarks • prediction of Higgs • quantum chromodynamics (QCD) Fig. : [3] TU Dresden Particles of the Standard Model Sophie Koßagk

  6. Definition The Standard Model of particle physics is a theory concerning the electromagnetic, weak, and strong nuclear interactions, which mediate the dynamics of the known subatomic particles. TU Dresden Particles of the Standard Model Sophie Koßagk

  7. Particle classification • half-integer spin (1/2, 3/2, …) • integer spin (1, 2, 3, …) Fig. : [4] TU Dresden Particles of the Standard Model Sophie Koßagk

  8. Fermions TU Dresden Particles of the Standard Model Sophie Koßagk

  9. Quarks • fractional electric charge • Colour charge • Colour confinement • Baryons (three quarks) and Mesons (two quarks) have an integer electric charge and they are colour neutral Fig.: [5] Fig. : [6] TU Dresden Particles of the Standard Model Sophie Koßagk

  10. Leptons • do not carry colour charge • Are not influence by strong force • Electron, muon, tau are single negative charged • Neutrinos has no charge TU Dresden Particles of the Standard Model Sophie Koßagk
