Nonperturbative QCD, gauge-fixing, Gribov copies, and the lattice [PDF]
Perturbative QCD uses the Faddeev-Popov gauge-fixing procedure, which leads to ghosts and the local BRST invariance of the gauge-fixed perturbative QCD action.

Vacuum correlators at short distances from lattice QCD
Non-perturbatively computing the hadronic vacuum polarization at large photon virtualities and making contact with perturbation theory enables a precision determination of the electromagnetic coupling at the Z pole, which enters global electroweak fits ...

Transport coeffcients from pQCD to the Hadron resonance gas at finite BSQ densities [PDF]
We calculate the shear viscosity, η, in two limits: perturbative QCD and an excluded-volume hadron resonance gas (HRG), at finite BSQ densities. Using an interpolation framework, we connect these regimes. In addition, we present results for (almost) next-

Quantum simulation of colour in perturbative quantum chromodynamics
Quantum computers are expected to give major speed-ups for the simulation of quantum systems. In this work, we present quantum gates that simulate the colour part of the interactions of quarks and gluons in perturbative quantum chromodynamics (QCD). As a

Tests of hard and soft QCD with e+e- Annihilation Data [PDF]
Experimental tests of QCD predictions for event shape distributions combining contributions from hard and soft processes are discussed. The hard processes are predicted by perturbative QCD calculations.

Abelian Decomposition and Monopole Condensation in QCD
We demonstrate the monopole condensation in QCD using the Abelian decomposition. The Abelian decomposition decomposes the gluons to the color neutral binding gluons (the neurons and the monopoles) and the colored valence gluons (the chromons), and shows ...

Experimental Tests Of Perturbative QCD [PDF]
The main experimental results to test quantum chromodynamics are reviewed. A wide variety of observables related to hard processes are correctly predicted by the theory, thus it is fair to say that the experimental support of QCD is quite solid and quantitative.(AIP)
