Nonperturbative mechanisms of strong decays in QCD
arXiv:hep-ph/0211410 · doi:10.1134/1.1625747
Abstract
Three decay mechanisms are derived systematically from the QCD Lagrangian using the field correlator method. Resulting operators contain no arbitrary parameters and depend only on characteristics of field correlators known from lattice and analytic calculations. When compared to existing phenomenological models, parameters are in good agreement with the corresponding fitted values.
