LICHARD Peter, prof. Ing. DrSc.

Course content

Theory of interacting fields. Symmetry and the interaction Lagrangians; electromagnetic interactions of scalar and spinor particles, pionnucleon 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. Electronpositron 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.
