Dynamical suppression of the spin-orbit interaction in hadrons
A. M. Badalian, A. V. Nefediev, Yu. A. Simonov
Spin-dependent interaction in hadrons is considered in the approach of the QCD string. The string moment of inertia, which ensures the correct (inverse) Regge slope 2*pi*sigma, is…
Spectra and decays of hybrid charmonia
Yu. S. Kalashnikova, A. V. Nefediev
QCD string model is employed to calculate the masses and spin splittings of lowest charmonium hybrid states with a magnetic gluon. Relative decay rates into various S- and P-wave D…
Radiative decays of hadronic molecules
A. V. Nefediev
It is argued that radiative decays of scalars a0/f0(980) can serve as a decisive tool in establishing the nature of the latter. In particular, predictions for the widths of the rad…
Nonperturbative dynamics in the colour-magnetic QCD vacuum
A. V. Nefediev, Yu. A. Simonov
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…
On Goldstone bosons decoupling from high-lying hadrons
L. Ya. Glozman, A. V. Nefediev
In this paper, we discuss a decoupling of the Goldstone bosons from highly excited hadrons in relation to the restoration of chiral symmetry in such hadrons. We use a generalised N…
QCD_2 in the axial gauge revisited
Yu. S. Kalashnikova, A. V. Nefediev
The 't Hooft model for the two-dimensional QCD in the limit of infinite number of colours is studied in the axial gauge. The mass-gap and the bound-state equations are derived usin…
