Background-Field Formalism in Nonperturbative QCD

The background-field formalism is used extensively in fundamental approaches to QCD to explore hadronic matrix elements of various currents. While the lattice QCD approach is formulated in the fully-interacting Hilbert space, which includes both QCD and background field interactions, the QCD sum-rule formalism is traditionally developed in the pure-QCD Hilbert space. The latter approach encount...

Nonperturbative dynamics in the colour – magnetic QCD vacuum

In the deconfinement phase of QCD quarks and gluons interact with the dense stochastic colour–magnetic vacuum. We consider the dynamics of quarks in this deconfinement phase using the Field Correlators Method and derive an effective nonperturbative interquark potential, in addition to the usual perturbative short–ranged interaction. We find the resulting angular–momentum–dependent interaction t...

Entanglement in the XZ spin chain model in the external magnetic field

The entanglement at zero-temperature is studied in a two-qubit XZ spin-1/2 chain model in anexternal magnetic field which is applied in the z direction. We have obtained an analytical relation forthe effect of the external magnetic field on the concurrence. It is shown that the ground state of thesystem depends on the strength of exchange coupling. We have shown that the analytical relation oft...

Testing Nonperturbative Ansätze for the QCD Field Strength Correlator

A test for the Gaussian and exponential Ansätze for the nonperturbative parts of the coefficient functions, D and D 1 , which parametrize the gauge-invariant bilocal correlator of the field strength tensors in the stochastic vacuum model of QCD, is proposed. It is based on the evaluation of the heavy-quark condensate within this model by making use of the world-line formalism and equating the o...

Baryon magnetic moments in the QCD string approach ( the Nonperturbative QCD approach )

Magnetic moments of baryons composed of light and strange quarks are computed for the first time through the only parameter of the model– string tension σ. For example, µ p = m p /c √ σ, µ Ω − = −µ p (1 + 3 4 m 2 s c 2 σ − 15 32 m 4 s c 4 σ 2) −1 , where magnetic moments are expressed in nuclear magnetons, m p is the proton mass, m s is the strange quark current mass, c = 0.957 – a constant whi...
