The course discusses modern techniques and applications of relativistic quantum field theory with an emphasis on path integral quantisation of non-abelian gauge theories and spontaneous breaking of symmetries.

A) Electroweak interactions- From the Fermi theory to the Standard Model (SM)- Spontaneous symmetry breaking and Higgs mechanism- Precision tests of the electroweak theoryB) Flavour Physics- The flavour sector of the SM- Neutral-meson mixing and rare decaysC) The SM as an effective theory- SM limitations and beyond-SM directions- Neutrino masses and neutrino oscillations
