Quark confinement in quantum chromodynamics [PDF]
Physical Review D, 1985 A quark-confinement mechanism inspired by renormalization-group-improved perturbative quantum chromodynamics is proposed. We obtain a quark-antiquark confining potential in the lowest approximation, show that it yields reasonable results for the bb\ifmmode\bar\else\textasciimacron\fi{} and cc\ifmmode\bar\else\textasciimacron\fi{} spin-averaged energy ...

Lattice Quantum Chromodynamics [PDF]
, 1985 It is generally accepted that relativistic field theory is relevant in high energy physics. It is also recognized that even in QCD, which is asymptotically free (i. e., the interactions become weak at high enough energies) the scope of perturbation theory is very limited.

New directions in Quantum Chromodynamics [PDF]
, 1999 Several topics in QCD are reviewed, including: the light-cone Fock state representation, which encodes the flavor, spin and other quark and gluon correlations of hadrons in the form of universal process-independent amplitudes; the light-cone factorization scheme for inclusive and exclusive processes; the application of the light-cone formalism to semi ...

Vision for QCD to the 2030s and Beyond
SciPost Physics Proceedings, 2022 In this closing talk, I review some of the lessons we've learned about quantum chromodynamics, and reflect on what we may hope to learn in the coming years.

The L ∞ structure of gauge theories with matter
Journal of High Energy Physics, 2021 In this work we present an algebraic approach to the dynamics and perturbation theory at tree-level for gauge theories coupled to matter. The field theories we will consider are: Chern-Simons-Matter, Quantum Chromodynamics, and scalar Quantum ...

Color screening in quantum chromodynamics [PDF]
Progress in Particle and Nuclear Physics, 2021 We review lattice studies of the color screening in the quark-gluon plasma. We put the phenomena related to the color screening into the context of similar aspects of other physical systems (electromagnetic plasma or cold nuclear matter). We discuss the onset of the color screening and its signature and significance in the QCD transition region, and ...

A Possible Resolution to Troubles of SU(2) Center Vortex Detection in Smooth Lattice Configurations
Universe, 2021 The center vortex model of quantum-chromodynamics can explain confinement and chiral symmetry breaking. We present a possible resolution for problems of the vortex detection in smooth configurations and discuss improvements for the detection of center ...

QUANTUM CHROMODYNAMICS AT COLLIDERS [PDF]
International Journal of Modern Physics A, 2006 QCD is the accepted (that is, the effective) theory of the strong interaction; studies at colliders are no longer designed to establish this. Such studies can now be divided into two categories. The first involves the identification of observables which can be both measured and predicted at the level of a few percent.
