Quantum Chromodynamics

The book is a self-contained introduction to perturbative and nonperturbative Quantum chromodynamics (QCD) with worked-out exercises for students of theoretical physics. It will be useful as a reference for research scientists as well. Starting with the hadron spectrum, the reader becomes familiar with the representations of SU(N). Relativistic quantum field theory is recapitulated, and scattering theory is discussed in the framework of scalar quantum electrodynamics. Then the gauge theory of quarks and gluons is introduced. In the more advanced chapters, perturbative and nonperturbative techniques in state-of-the-art QCD are discussed in great detail. The new third edition has been extensively revised and enlarged to cover all new aspects in Quantum chromodynamics. We are pleased by the positive resonance of our book which now necessitates a fourth edition. We have used this opportunity to implement corrections of misprints and amendments at several places, and to extend and improve the discussion of many of the exercises and examples. We hope that our presentation of the method of equivalent photons (Example 3. 17), the form factor of the electron (Example 5. 7), the infrared catastrophe (Example 5. 8) and the energy shift of atomic levels (Example 5. 9)arenow even better to understand. The new Exercise 5. 10 shows in detail how to arrive at the non-relativistic limit for the calculation of form factors. Moreover, we have brought up-to-date the Biographical Notes about physicists who have contributed to the dev- opment of quantum electrodynamics, and references to experimental tests of the t- ory. For example, there has been recent progress in the determination of the electric and magnetic form factors of the proton (discussed in Exercise 3. 5 on the Rosenbluth formula) and the Lamb shift of high-Z atoms (discussed in Example 5. 9 on the energy shift of atomic levels), while the experimental veri cation of the birefringence of the QED vacuum in a strong magnetic eld (Example 7. 8) remains unsettled and is a topic of active ongoing research. This Introduction To Perturbative And Nonperturbative Quantum Chromodynamics (qcd) Has Worked Exercises For Students Of Theoretical Physics. In The More Advanced Chapters, Perturbative And Nonperturbative Techniques In State-of-the-art Qcd Are Discussed In Great Detail.

this Textbook On Quantum Electrodynamics Is A Thorough Introductory Text Providing All Necessary Mathematical Tools Together With Many Examples And Worked Problems. In Their Presentation Of The Subject The Authors Adopt A Heuristic Approach Based On The Propagator Formalism. The Latter Is Introduced In The First Two Chapters In Both Its Nonrelativistic And Relativistic Versions. Subsequently, A Large Number Of Scattering And Radiation Processes Involving Electrons, Positrons, And Photons Are Introduced And Their Theoretical Treatment Is Presented In Great Detail. Higher Order Processes And Renormalization Are Also Included. The Book Concludes With A Discussion Of Two-particle States And The Interaction Of Spinless Bosons. This Completely Revised And Corrected New Edition Provides Several Additions To Enable Deeper Insight In Formalism And Application Of Quantum Electrodynamics.

The third edition of this outstanding volume has been extensively revised and enlarged to cover all new aspects in Quantum chromodynamics. It first reviews relativistic quantum field theory and details scattering theory in the framework of scalar quantum electrodynamics. The book then introduces the gauge theory of quarks and gluons. In addition, more advanced chapters present a through discussion of perturbative and nonperturbative techniques in state-of-the-art QCD. Throughout, worked-out examples provide hands-on experience for students in theoretical physics. Research scientists will also find the book an ideal reference. A book on Quantum Electrodynamics that provides the necessary mathematical tools together with many examples and worked problems. It introduces various number of scattering and radiation processes involving electrons, positrons, and photons; and also presents their theoretical treatment.
