Book Description

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

• Contains up-to-date descriptions of the most important form factors of the electroweak transitions investigated in particle physics experiments

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.


Form factors are certain functions that characterise distribution and flow of matter inside extended objects and are very common in particle and hadron physics. The book by A. Khodjamirian provides a general review of this broad topic at the level accessible for graduate students. The standard course in the theory of strong interactions, Quantum Chromodynamics, should be a prerequisite.

The book is addressed to students specialising in QCD phenomenology who want to familiarize themselves with the general concepts and learn how the calculations of hadron form factors are done in practice using several standard methods, without digging too much in the theory background. It will also be useful for experimenalists who are interested in an overall picture and want to understand where the theory predictions come from.

The last three chapters contain a somewhat more advanced material as compared to the rest of the book.

They will be very useful for practitioners as an introduction to the techniques of QCD sum rule calculations.
