Περιεχόμενα
- 1. Introduction: : PDF
Quantum fields and natural units.
Some history: X-rays, alpha and beta radiation, the electron, the proton, and the neutron. - 2. A First Look at Quantum Fields: PDF
Matter fields and force fields, bosons and fermion. Spin, the Dirac eqaution, and anti-matter. Quantum electrodynamics, Feynman diagrams. Renormalisation.
Some history: Cosmic rays, the positron, the muon and the pion. - 3. The Strong Force: PDF
Yang-Mills theory, gluons, asymptotic freedom and the mass gap. Quarks and colour. Baryons, mesons and the eightfold way.
Some history: The cyclotron and synchrotron. Resonances, anti-protons, deep inelastic scattering, charmonium, and the top quark. - 4. The Weak Force: PDF
The structure of the Standard Model, parity violation, quantum anomaly cancellation. The Higgs field, the Higgs potential, W- and Z-bosons, and the weak decays. Flavours of fermions, Yukawa interactions, symmetry breaking, quark mixing, CP violation and time reversal, conservation laws. Neutrinos, neutrino masses and neutrino oscillations.
Some history: the discovery of neutrinos, the theta-tau puzzle, bosons at CERN, and neutrino oscillations. - 5. What We Don’t Know: PDF
Beyond the Standard Model, unification, naturalness and fine-tuning, axions. General relativity and quantum gravity. Cosmology, the cosmological constant, dark matter, baryogenesis, primordial fluctuations.
