Particles of the Standard Model

This presentation provides an overview of the Standard Model of particle physics, explaining its significance in understanding the fundamental forces and particles that constitute the universe. It covers key topics including a historical introduction, classification of particles (fermions, quarks, leptons, gauge bosons, and the Higgs boson), and essential concepts such as quantum electrodynamics and chromodynamics. The Standard Model serves as a crucial framework for understanding electromagnetic, weak, and strong nuclear interactions, paving the way for contemporary physics research.

  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
