This book was originally published in 1980. Theoretical physics makes
extensive use of models to test and develop intuition. This monograph
seeks to provide an introduction to high-energy model making. Its aim is
to explain the basic ideas in a form accessible to graduate students and
other readers who have acquired a first-hand knowledge of quantum field
theory and basic particle physics, including the elements of Regge
theory. It describes major calculational techniques together with
sufficient physical applications to illustrate their utility. No attempt
has been made to be encyclopaedic, for an exhaustive treatment of every
application would have created a volume too large for the simple
pedagogic purpose intended.
