Quantum Field Theory

This comprehensive text offers a balanced treatment of quantum field theory, providing both a formal presentation and numerous practical examples. A two-part approach, it begins with the standard quantization of electrodynamics, culminating in the perturbative renormalization. The second part comprises functional methods, relativistic bound states, broken symmetries, nonabelian gauge fields, and asymptotic behavior. Appropriate for students and researchers in field theory, particle physics, and related areas, this treatment presupposes a familiarity with quantum mechanics, electrodynamics, relativity, and classical calculus, including group theory and complex analysis. 1980 ed. 157 figures.
