Coupled-channel model for charmonium levels and an option for X(3872)
Yu. S. Kalashnikova
The effects of charmed meson loops on the spectrum of charmonium are considered, with special attention paid to the levels above open-charm threshold. It is found that the coupling…
Generalized Weinberg's approach to the a0/f0 case
Yu. S. Kalashnikova
The problem of whether it is possible to distinguish composite from elementary particles is studied in the framework of Weinberg's approach. The possibility to extend this approach…
Two-dimensional QCD in the Coulomb gauge
Yu. S. Kalashnikova, A. V. Nefediev
In the present paper we discuss various aspects of the 't Hooft model for two-dimensional QCD in the limit of infinite number of colours in the Coulomb gauge. The properties of mes…
Hybrid mesons: old prejudices and new spectroscopy
Yu. S. Kalashnikova
The models for hybrid mesons are discussed, in which the gluonic excitations manifest themselves as the vibrations of the quark- antiquark QCD string. The predictions for the spect…
Hybrid states
Yu. S. Kalashnikova
Theoretical arguments are given in favour of existence of gluonic degrees of freedom at the constituent level. Models for hybrid mesons are discussed, and the predictions are compa…
Constituent gluons from QCD
Yu. S. Kalashnikova
The notion of constituent gluon is introduced as a gluon propagating in the vacuum background field. The Hamiltonian approach for a system containing such gluon and a p…
