Quantum Chromodynamics: Perturbative and Nonperturbative Aspects (Cambridge Monographs on Particle Physics, Nuclear Physics and Cosmology)

Introduction

Quantum Chromodynamics: Perturbative and Nonperturbative Aspects, part of the eminent Cambridge Monographs on Particle Physics, Nuclear Physics, and Cosmology series, is a profound exploration of one of the most significant components of modern theoretical physics: quantum chromodynamics (QCD). This book delves into the foundational principles, mathematical formulations, and real-world applications of QCD, providing a comprehensive account of both its perturbative and nonperturbative domains. Authored by three of the field’s towering figures — B. L. Ioffe, V. S. Fadin, and L. N. Lipatov — this work serves as a crucial resource for physics researchers, graduate students, and anyone with a strong interest in the fundamental forces governing our universe.

QCD, the quantum field theory describing the strong interaction between quarks and gluons, lies at the heart of the Standard Model of particle physics. The book shines a light on this elegant theory, explaining how its principles dictate the stability of matter, the behavior of elementary particles, and the origins of nuclear forces. By covering both the high-energy, perturbative regime of QCD and the challenging, low-energy nonperturbative aspects, this book provides unparalleled insights into the theoretical richness of modern physics.

Detailed Summary of the Book

At its core, this book serves as a comprehensive guide to understanding QCD in its full complexity. The content is systematically organized, starting with fundamental principles and gradually progressing to advanced concepts and research frontiers. The authors detail the development of QCD as part of the Standard Model, reviewing its historical origin and key experimental confirmations. Foundational chapters cover topics such as color charge as the source of the strong force, the confinement of quarks and gluons, and the phenomenon of asymptotic freedom.

A significant portion of the book is devoted to perturbative QCD (pQCD), the domain where calculations are possible using perturbation theory due to the smallness of the strong coupling constant at high energies. Techniques such as renormalization, parton distribution functions, and QCD factorization are explained in detail with mathematical rigor and physical intuition. These sections shed light on the intricacies of high-energy particle collisions, the behavior of jets, and the role of QCD in processes at modern particle colliders like the Large Hadron Collider (LHC).

The nonperturbative aspects of QCD, which address the physics of low-energy interactions and confinement, form another cornerstone of the book. Topics include lattice QCD, effective field theories, instantons, and the QCD vacuum structure. These discussions not only emphasize the theoretical challenges but also highlight the relevance of these concepts to the study of hadrons, glueballs, and other strongly interacting systems.

Throughout the book, the authors seamlessly blend theoretical discussions with experimental insights, demonstrating the close interplay between theory and observation. Additionally, state-of-the-art topics such as QCD in heavy ion collisions, the quark-gluon plasma, and the connection between QCD and modern nonperturbative approaches like the AdS/CFT correspondence are covered, making this monograph a true treasure trove of knowledge for researchers in the field.
