Elementary Processes at High Energy, Part A covers the proceedings of the eighth Course of The International School of Subnuclear Physics held in Erice, Italy, in July 1970. The said conference is focused on the study of phenomenological approaches to particle physics as well as other specialized topics in the field. The book is divided into three parts. Part 1 discusses electron position annihilators; weak interactions; and hadron processes at higher energies. Part 2 covers topics such as rigorous results from field theory and unitarity; finite theory of quantum electrodynamics; and models for hadronic reactions. Part 3 topics include gravitation; symmetry principles in physics; and electromagnetic production of hadronic resonances. The text is recommended for physicists, especially those who are interested in the developments in the field of particle physics.
