Renormalization: An Introduction to Renormalization, the Renormalization Group and the Operator-Product Expansion - Paperbackby John C. Collins (Author) Many numerical predictions of experimental phenomena in particle physics are made possible by exploiting the discovery that simplifications can happen when phenomena are investigated on short distance and time scales. This book provides a coherent exposition of the renormalization techniques underlying these calculations. After reminding the reader of some basic properties of field theories, examples are used to explain the
