The Odderon in QCD with running coupling
Journal of High Energy Physics, 2020 Starting from the leading Odderon solution of the three gluon system in perturbative QCD we introduce, as a first step towards the transition to the non-perturbative region, an infrared cutoff and use the running QCD coupling constant.

AN ANALYTIC APPROACH TO PERTURBATIVE QCD [PDF]
International Journal of Modern Physics A, 2000 The two-loop invariant (running) coupling of QCD is written in terms of the Lambert W function. The analyticity structure of the coupling in the complex Q2-plane is established. The corresponding analytic coupling is reconstructed via a dispersion relation.

Experimental Tests Of Perturbative QCD [PDF]
Annual Review of Nuclear and Particle Science, 1989 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)

The high-energy limit of perturbative QCD: Theory and phenomenology
, 2022 After a brief introduction of formal and phenomenological progresses in the study of the high-energy limit of perturbative QCD, we present arguments supporting the statement that the inclusive emission of Higgs bosons or heavy-flavored hadrons acts as ...

QCD equation of state and dark matter [PDF]
, 2012 The QCD equation of state is not often discussed in cosmology. However, the relic density of weakly interacting massive particles (WIMPs) depends on the entropy and the expansion rate of the Universe when they freeze out, at a temperature in the range ...

Abelian Decomposition and Monopole Condensation in QCD
EPJ Web of Conferences, 2018 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 ...

Transport coeffcients from pQCD to the Hadron resonance gas at finite BSQ densities [PDF]
EPJ Web of ConferencesWe 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-

Vacuum correlators at short distances from lattice QCD
Journal of High Energy Physics, 2021 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 ...

THE TRANSITION BETWEEN PERTURBATIVE AND NON-PERTURBATIVE QCD [PDF]
Quark-Hadron Duality and the Transition to PQCD, 2006 We study both polarized and unpolarized proton structure functions in the kinematical region of large Bjorken x and four-momentum transfer of few GeV^2. In this region the phenomenon of parton-hadron duality takes place between the smooth continuation of the deep inelastic scattering curve and the average of the nucleon resonances.
