This book examines the various types of transitions on hadron states according to the quark model. Emphasizing the non-relativistic quark model, with a study of relativistic corrections, the authors describe methods and summarize the model's experimental status. They give detailed examinations of processes induced by the electromagnetic, weak and strong interactions, with a systematic comparison of the model with experiment. Hadron Transitions in the Quark Model constitutes a possible synthesis of the impressive achievements of the quark models in this low energy domain, and is addressed to experimental and theoretical particle physicists.
