Publisher's Synopsis
Requiring no prior knowledge of the subject, A First Book of Quantum Field Theory introduces the subject as an elegant yet relatively simple piece of machinery with a broad range of applications. This treatment takes a rather unique approach through decay processes, which are, in some ways, simpler than scattering processes and their use allows the authors to introduce the basic machinery of Feynman diagrams even before addressing the quantization of spin-1 fields. With clear, engaging prose, strategically placed exercises, and canonical quantization employed throughout, this book offers a treatment ideal for advanced undergraduate and beginning post-graduate students.
