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

Soft Graviton Emission at High and Low Energies in Yukawa and Scalar Theories
TL;DR: In this article, the soft graviton theorem is corrected by matrix elements coupled to the Riemann curvature tensor tensor of linearized gravity, and the role played by the external kinematics.

Mapping the internal structure of hadrons through color and spin effects
TL;DR: In this paper, the Boer-Mulders function is used to describe correlations between the spin and transverse momentum of quarks inside the proton, which gives rise to a very specific asymmetry in the directions of produced particles.

TL;DR: In this paper, the authors review the prospects for quarkonium-production studies in proton and nuclear collisions accessible during the upcoming phases of the CERN Large Hadron Collider operation after 2021, including the ultimate high-luminosity phase, with increased luminosities compared to LHC runs 1 and 2.

The Effective Vector Boson Approximation in High-Energy Muon Collisions.
TL;DR: In this paper, the authors investigated universal and quasi-universal power-law and logarithmic corrections that arise when deriving (polarized) weak boson PDFs in the collinear limit.
