Semenov ( Center for Gravitation and Fundamental Metrology, VNIIMS, Moscow, Institute of Nuclear Physics, Moscow State University, Russian Research Center "Kurchatov Institute", Moscow | | Abstract: | In the framework of the relativistic independent quark model the parameters of the QCD-motivated static potential and the quark masses are calculated on the basis of the $1^{--}$ meson mass spectra. The value of the confining potential coefficient is found to be ($0.197pm 0.005) GeV${}^2$. for quark- antiquark interaction independently on their flavours. The dependence of the quasi-Coulombic potential strength on the interaction distance are consistent with the QCD-motivated behaviour. The $qar q$-separations are evaluated and the $e^+e^-$ decay widths are estimated with the help of relativistic modification of the Van Royen-Weisskopf formula. | | Source: | arXiv, hep-ph/0111055 | | Services: | Forum | Review | PDF | Favorites | |
