Unveiling the Mysteries: Foundations of Perturbative QCD

The realm of particle physics is a captivating field that delves into the fundamental building blocks of the universe. Among the various theories that attempt to explain the behavior of these particles, one of the most influential and extensively studied is Perturbative Quantum Chromodynamics (pQCD). Developed over decades of scientific research, this framework has revolutionized our understanding of the strong nuclear force and the interactions between quarks and gluons.

What is Perturbative QCD?

Perturbative QCD, often referred to as pQCD, is a branch of theoretical physics that focuses on simulating and calculating the interactions between quarks and gluons within the context of Quantum Chromodynamics (QCD). QCD is a theory that describes the strong nuclear force, which is responsible for holding atomic nuclei together.

Unlike other fundamental forces, such as electromagnetism, the strong force becomes stronger at higher energies and shorter distances. This phenomenon, known as "asymptotic freedom," led to the development of pQCD as a calculational tool. By treating interactions between quarks and gluons as a perturbation of the QCD vacuum, pQCD allows physicists to make precise predictions about the behavior of particles at high energies.

The most non-trivial of the established microscopic theories of physics is QCD: the theory of the strong interaction. A critical link between theory and experiment is provided by the methods of perturbative QCD, notably the well-known factorization theorems. Giving an accurate account of the concepts, theorems and their justification, this book is a systematic treatment of perturbative QCD. As well as giving a mathematical treatment, the book relates the concepts to experimental data, giving strong motivations for the methods. It also examines in detail transverse-momentum-dependent parton densities, an increasingly important subject not normally treated in other books. Ideal for graduate students starting their work in high-energy physics, it will also interest experienced researchers wanting a clear account of the subject.
