Narrow-width tetraquarks in large-Nc QCD
The properties of possibly existing tetraquarks are studied in the large-Nc limit of QCD by means of four-point correlation functions of meson currents. The necessity of a detailed analysis of the singularities of Feynman diagrams, by means of the Landau equations, to recognize those diagrams that m...
