- Cíle předmětu
- To acquaint students with the theory of interacting quantum fields and its applications, in particular spinor electrodynamics. The cross-sections of selected processes are calculated in detail in lectures, tutorial sessions, and also in the framework of individual work of students.
- Osnova
- Theory of interacting fields. Symmetry and the interaction Lagrangians; electromagnetic interactions of scalar and spinor particles, pion-nucleon interaction. Local gauge invariance. Dirac's picture, Moeller's operator. S and T operator, their matrix elements (case of the normalization to the final volume and that of the continuous momentum spectrum). Transition amplitude, decay rate, cross section. Perturbation expansion of the S operator, invariant perturbation method. Wick's theorem.
Spinor electrodynamics. Amplitudes of the Compton's, Moeller´s and Bhabha´s scattering obtained from the invariant perturbation method. Feynman diagrams and rules. Processes with charged leptons of various types.
Scalar electrodynamics. Electron-positron annihilation into two (point) pions. Feynman rules.
Weak interactions in the lepton sector. Neutrinos, gauge bosons, the interaction Lagrangian. Parity violation. Lepton decay of the W boson, muon decay.
