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

Ground state pseudoscalar mesons on the light front: from the light to heavy sector.
TL;DR: In this article, the leading Fock-state light front wave functions (LF-LFWFs) of both the light and heavy pseudoscalar mesons, e.g., the pion (at masses of 130 MeV, 310 MeV and 690 MeV), were extracted from their covariant Bethe-Salpeter wave functions within the rainbow-ladder truncation.

Structure constants of twist-two light-ray operators in the triple Regge limit
TL;DR: In this paper, the structure constants of twist-two light-ray operators with spin $j$ in the BFKL limit were determined from the calculation of the three-point correlator of the twist two lightray operators in the triple Regge limit.

Double parton scattering in the ultraviolet: addressing the double counting problem
Markus Diehl,Jonathan R. Gaunt +1 more
TL;DR: In this article, a consistent approach for solving this problem, which retains the notion of double parton distributions (DPDs) for individual hadrons, is described, and the construction of appropriate model DPDs in their framework, and they discuss the use of these to compute the DPS part, presenting DPS 'luminosities' from their model DPMs for a few sample cases.
