Learning outcomes

After passing the course the student should be able to

  • discuss the main aspects, assumptions and predictions of the theory of the strong interaction, in particular asymptotic freedom, confinement and chiral symmetry breaking
  • explain the concepts of scale separation and effective degrees of freedom and relate them to the general framework of effective field theories
  • analyse the symmetries of a system and account for their importance in the understanding of particle physics
  • relate the properties of quarks and gluons to the properties of their composite objects, the hadrons
  • calculate reaction and decay rates starting from a Lagrangian
