Quantum Chromodynamics at High Energy

Abstract

"Filling a gap in the current literature, this book is the first entirely dedicated to high energy quantum chromodynamics (QCD) including parton saturation. It presents groundbreaking progress on the subject and describes many problems at the forefront of research, bringing postgraduate students, theorists, and advanced experimentalists up to date with the current state of research in this field. A broad range of topics in high energy QCD is covered, most notably on the physics of parton saturation and the color glass condensate (CGC). The clear, helpful presentation includes numerous examples and exercises. Discussion ranges from the quasi-classical McLerran-Venugopalan model to the linear BFKL and nonlinear BK/JIMWLK small-x evolution equations. The authors' outlook embraces both theory and experiment and the physics of strong interactions is presented in a universal way, making it applicable to physicists from various subcommunities and to processes studied at all high energy accelerators around the world.
