Progress in perturbative QCD [PDF]
AIP Conference Proceedings, 1997 We briefly summarize some recent theoretical developments in perturbative QCD, emphasizing new ideas which have led to widening the domain of applicability of perturbation theory.

Sudakov Safety in Perturbative QCD [PDF]
Physical Review D, 2015 Traditional calculations in perturbative quantum chromodynamics (pQCD) are based on an order-by-order expansion in the strong coupling ${\ensuremath{\alpha}}_{s}$.

Non-perturbative to perturbative QCD via the FFBRST [PDF]
European Physical Journal C: Particles and Fields, 2018 Recently a new type of quadratic gauge was introduced in QCD in which the degrees of freedom are suggestive of a phase of abelian dominance. In its simplest form it is also free of Gribov ambiguity.

Multiparticle production and perturbative QCD [PDF]
Surveys in High Energy Physics, 2001 The perturbative quantum chromodynamics (QCD) is quite successful in the description of main features of multiparticle production processes. Ten most appealing characteristics are described in this brief review talk and compared with QCD predictions. The

, 1994 This is the written version of a set of lectures on perturbative QCD that were delivered to a mixed audience of young theorists and experimentalists in the course of the XXII International Meeting on Fundamental Physics. These notes are virtually a verbatim transcription of the lectures.

Introduction to Perturbative QCD [PDF]
arXiv, 1997 This is a written version of two lectures given at the First School on Field Theory and Gravitation in Vitoria (Brasil) April 15-19, 1997. We discuss the foundation of QCD as the theory of strong interactions and the perturbative analysis of e^+e^- annihilation into hadrons. Typical concepts of perturbative QCD studies, such as collinear singularities,

Perturbative QCD and the neutron star equation of state [PDF]
Physical Review C, 2022 We construct a physics-agnostic approach to the neutron star (NS) equation of state (EoS) based on a sound speed model, which connects both low-density information from nuclear theory and high-density constraints from perturbative QCD (pQCD).

How Perturbative QCD Constrains the Equation of State at Neutron-Star Densities. [PDF]
Physical Review Letters, 2021 We demonstrate in a general and analytic way how high-density information about the equation of state (EOS) of strongly interacting matter obtained using perturbative quantum chromodynamics constrains the same EOS at densities reachable in physical ...

R2-gravity quark stars from perturbative QCD [PDF]
Journal of Cosmology and Astroparticle Physics, 2021 We investigate the structure of quark stars in the framework of f(R)= R + αR 2 gravity using an equation of state for cold quark matter obtained from perturbative QCD, parametrized only by the renormalization scale.
