Field correlators in QCD. Theory and applications. Abstract This review is dedicated to the study of nonabelian gauge theories by making use of the gauge-invariant nonlocal field correlators. Basicâ€¦ (More)

Perturbative expansion in the nonperturbative confining QCD background is formulated. The properly renormalized Î± S (R) is shown to be finite at large distances, with the string tension playing theâ€¦ (More)

Mechanism of di-pion transitions nS â†’ n â€² SÏ€Ï€(n = 3, 2; n â€² = 2, 1) in bottomonium and charmonium is studied with the use of the chiral string-breaking Lagrangian allowing for the emission of anyâ€¦ (More)

It is argued that the dominant contribution to the interaction of quark gluon plasma at moderate T â‰¥ T c is given by the nonperturba-tive vacuum field correlators. Basing on that nonperturbativeâ€¦ (More)

Using a nonperturbative method based on asymptotic behaviour of Wilson loops we calculate masses of glueballs and corresponding Reggeâ€“trajectories. The method contains no fitting parameters and theâ€¦ (More)

This is an extended version of the paper hep-th/9802134. Dual QCD Lagrangian is derived by making use of the coordinate gauge of general type where the 1-form (vector potential) is expressed as aâ€¦ (More)

It is shown that analytic properties of standard QCD perturbation theory contradict known spectral properties,and contain in particular IR generated ghost poles and cuts. As an outcome the rigorousâ€¦ (More)

The spectra of lightâ€“light and heavyâ€“light mesons are described by spinless Salpeter equation and Dirac equation respectively, which predict linear dependence of the meson mass squared M 2 on angularâ€¦ (More)

An effective Lagrangian for the light quark in the field of a static source is derived systematically using the exact field correlator expansion. The lowest Gaussian term is bosonized using nonlocalâ€¦ (More)

Field distributions generated by static QQÌ„ and QQQ sources are calculated analytically in the framework of Gaussian (bilocal) approximation of Field Correlator Method. Special attention is paid toâ€¦ (More)
