We investigate the infrared behaviour of gluon and ghost propagators in Landau gauge QCD by means of an exact renormalisation group equation. We explain how, in general, the infrared momentum… (More)

We investigate the infrared behavior of gluon and ghost propagators in Landau-gauge QCD by means of an exact renormalization group equation. We explain how, in general, the infrared momentum… (More)

The transition form factor F γπ (Q 2), decay width Γ(π 0 → γγ) and charge form factor of pion F π (Q 2) are calculated within the model of induced non-local quark currents based on the assumption… (More)

We address the computation of the determinant for the Dirac operator corresponding to a quark propagating in a background gluon field of the following type: the gauge field is covariantly constant… (More)

Implementation of the automated input data flow generation algorithms for the air traffic control simulator is likely to help to use the advantages of individual-based training better. The article… (More)

The transition form factor F γπ (Q 2), decay width Γ(π 0 → γγ) and charge form factor of pion are calculated within the model of induced nonlocal quark currents based on the assumption that the… (More)

We discuss how the inclusion of singular gauge fields in the partition function for QCD can lead to a domain-like picture for the QCD vacuum by virtue of specific conditions on quantum fluctuations… (More)

Singular gauge fields in the partition function for QCD can lead to a domain-like picture for the QCD vacuum by virtue of constraints on quantum fluctuations at the singularities. With a simple model… (More)
