Investigating the Tetraquark Structure of the New Mesons
Using the QCD sum rule approach we investigate the vertex associated with the decay D0(0+) ! D+p¡,where the scalar meson D0(0+) is considered as a four-quark state (cd)(u¯d¯). Although our results for themass and partial decay width are smaller than the mass and the total decay width of the broad sc...
