Unified Model of Weak and Electromagnetic Interactions
If one measures the success of a physical theory by the accuracy of its theoretical predictions as compared with experiments, Quantum Electrodynamics is the most successful theory in science. No wonder, that it was then chosen as a model after which other physical theories — in particular Weak Interactions — where designed. Naturally, there are some distinct differences such as violation of parity or hypercharge. in Weak Interactions. The stumbling block which prevented the “classical” V-A theory of Weak Interactions to become as elegant and as powerfully predictive as Quantum Electrodynamics, is the fact that no quanta — let alone low mass quanta — of Weak Interactions have been found so far. The celebrated intermediate boson shall be assumed to exist throughout our lectures but it is its high mass (low mass values being ruled out experimentally) which renders the classical theory of Weak Interactions non-renormalizable.
