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+pi-, where the scalar meson D0(0+) is considered as a four-quark state $(cd)(\bar{u}\bar{d})$. Although our results for the mass and partial decay width are smaller than the mass and the total decay wid...
