It gives a concise introduction to advanced concepts that are important for research in elementary particle theory. Topics include the path integral, loop expansion, Feynman rules, various regularization methods, renormalization, running couplings and the renormalization group, fixed points and asymptotic freedom, effective action, Coleman-Weinberg effective potential, fermions, the axial anomaly, QED, gauge fixing, nonabelian gauge theories, unitarity, optical theorem, Slavnov-Taylor identities, beta function of Yang-Mills theory, a heuristic derivation of asymptotic freedom, instantons in SU(N) gauge theory, theta vacua and the strong CP problem. Exercises are included and are intended for advanced graduate students or postdocs seeking to deepen their understanding of QFT.SpringerBriefs in Physics,2191-5431Particles (Nuclear physics)Quantum field theoryElementary Particles, Quantum Field TheoryParticles (Nuclear physics)Quantum field theory.Elementary Particles, Quantum Field Theory.530.143530.143Cline James M.1960-845491MiAaPQMiAaPQMiAaPQBOOK9910739468703321Advanced concepts in quantum field theory1887559UNINA
