Foundations of Perturbative QCD
TLDR
In this paper, a systematic treatment of perturbative QCD is given, giving an accurate account of the concepts, theorems and their justification, giving strong motivations for the methods.Abstract:
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.read more

Systematic analysis of double-scale evolution
TL;DR: In this article, the authors considered the transverse momentum dependent distributions (TMD) and defined an optimal TMD distribution, which is a scaleless model-independent universal non-perturbative function.

TL;DR: In this paper, an operator-based factorization theorem for the energy-energy correlation (EEC) observable in the back-to-back region was derived, allowing the cross section to be written as a convolution of hard, jet and soft functions.

Geometric IR subtraction for real radiation
TL;DR: In this article, a local slicing procedure is proposed for the subtraction of soft and collinear divergences present in massless real emission phase space integrals, which is based on the soft-and-collinear factorization properties of amplitudes.
