Advanced experimental physics: Particle and astroparticle physics
Time and place
Solid knowledge of the topics covered in EP-5 (Kern- und Teilchenphysik) is highly recommended.
This lecture provides a deeper introduction into particle and astroparticle physics. It builds upon the competences and knowledge gained in EP-5. Topics: - Introduction: particle zoo, interactions and exchange particles, relativistic kinematics, Feynman diagrams - Covariant description of relativistic particles: Klein-Gordon equation, crossing symmetry, invariant amplitude and cross section, Fermi's Golden Rule - Quantum electrodynamics of spin-less particles: covariant electrodynamics, photon propagator, Feynman rules, scattering cross section - Quantum electrodynamics of spin-1/2 particles: Dirac equation, electron-muon scattering cross section, helicity conservation, electron-positron scattering - Weak Interactions: charged-current interactions, V-A structure, parity violation, quark couplings and CP violation - Physics of massive neutrinos: neutrino oscillations, mass hierarchy, double beta decay - Towards the Standard Model of Particle Physics: neutral current interactions, weak isospin and hypercharge, electroweak unification - The Higgs mechanism: gauge invariance, spontaneous symmetry breaking, Higgs couplings, Higgs production and decay - Beyond the Standard Model: introduction to supersymmetry, Dark Matter
