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. 410 0$aSpringerBriefs in Physics,$x2191-5431 606 $aParticles (Nuclear physics) 606 $aQuantum field theory 606 $aElementary Particles, Quantum Field Theory 615 0$aParticles (Nuclear physics) 615 0$aQuantum field theory. 615 14$aElementary Particles, Quantum Field Theory. 676 $a530.143 676 $a530.143 700 $aCline$b James M.$f1960-$0845491 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910739468703321 996 $aAdvanced concepts in quantum field theory$91887559 997 $aUNINA
