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

Precision QCD at the LHC: from the structure of the proton to all-order resummations
TL;DR: In this article, the authors present two global PDF sets where fixed-order calculations are supplemented by threshold and high-energy resummation, respectively, for the Higgs transverse-momentum spectrum both in the inclusive case and within fiducial cuts.

Basics of factorization in a scalar Yukawa field theory
TL;DR: In this paper , the authors present the steps of factorization in a real scalar Yukawa field theory for both deep inelastic scattering (DIS) and semi-inclusive DIN (SIDIS) cross sections.

Quark-sector Lorentz violation in $Z$-boson production
TL;DR: In this article, the first two generations of quarks were studied in the context of Drell-Yan dilepton production including effects from Z-boson exchange, and the chiral nature of the weak interactions enables parity-violating and spin-dependent effects to be studied using unpolarized initial states.
Unpolarized transverse-momentum dependent distribution functions of a quark in a pion with Minkowskian dynamics
TL;DR: In this paper , the authors propose a solution to solve the problem of the problem: this paper ] of "uniformity" and "uncertainty" of the solution.

Drell-Yan angular lepton distributions at small $x$ from TMD factorization.
TL;DR: In this article, the DY hadronic tensors are expressed in terms of quark and quark-gluon TMDs with ${1\over Q^2}$ and ${ 1\over N_c^2}) accuracy.
