This book introduces the phenomenology and theory of hadron form factors in a consistent manner, deriving step-by-step the key equations, defining the form factors from the matrix elements of hadronic transitions and deriving their symmetry relations. Explained are several general concepts of particle theory and phenomenology exemplified by hadron form factors. The main emphasis here is on learning the analytical methods in particle phenomenology. Many examples of hadronic processes involving form factors are considered, from the pion electromagnetic scattering to heavy B-meson decays. In the second part of the book, modern techniques of the form factor calculation, based on the method of sum rules in the theory of strong interactions, quantum chromodynamics, are introduced in an accessible manner.
This book will be a useful guide for graduate students and early-career researchers working in the field of particle phenomenology and experiments.
• The first book to address the phenomenology of hadron form factors at a pedagogical level in one coherent volume

Alexander Khodjamirian is a professor at the Department of Physics, University of Siegen, Germany. Dr. Khodjamirian received his PhD degree in theoretical physics from the Yerevan Physics Institute in 1980, where he later worked as a staff member in the Theory Division. In 1992 he moved to Germany, first as a Humboldt Fellow at Ludwig-Maximilian University in Munich, then as a research associate and visitor at various universities and research centers in Germany and Europe (LMU in Munich, University of Würzburg, NBI in Copenhagen, CERN, University of Lund, University of Karlsruhe). From 2004 he worked as a senior staff scientist, before becoming a professor at the University of Siegen in 2009. Prof. Dr. Khodjamirian is a foreign member of the Armenian National Academy of Sciences. He is highly respected in his field of scientific research, which is theoretical particle physics, quantum chromodynamics and the phenomenology of hadrons.
