Written by world-leading experts in particle physics this new book from Luciano Maiani and Omar Benhar with contributions from the late Nicola Cabibbo is based on Feynmanâs path integrals. Key elements of gauge theories are describedâFeynman diagrams gauge-fixing Faddeev-Popov ghostsâas well as renormalization in Quantum Electrodynamics. Quarks and QCD interactions are introduced. Renormalization group and high momentum behaviour of the coupling constants is discussed in QED and QCD with asymptotic freedom derived at one-loop. These concepts are related to the Higgs boson and models of grand unification. â an excellent introduction to the quantum theory of gauge fields and their applications to particle physics. â It will be an excellent book for the serious student and a good reference for the professional practitioner. Let me add that scattered through the pages we can find occasional traces of Nicola Cabibbo's style. âJohn Iliopoulos CNRS-Ecole Normale SupÃrieure â The volume ends with an illuminating description of the expectation generated by the recent discovery of the Higgs boson combined with the lack of evidence for super-symmetric particles in the mass range 0. 6-1 TeV. âArturo Menchaca-Rocha FinstP Professor of Physics Mexicoâs National Autonomous University Former President of the Mexican Academy of Sciences Presidential Advisor âThe reader is masterfully guided through the subtleties of the quantum field theory and elementary particle physics from simple examples in Quantum Mechanics to salient details of modern theory. âMikhail Voloshin Professor of Physics University of Minnesota .
