Diquark-Antidiquark with open charm in QCD sum rules

M. Nielsen, R. D. Matheus, F. S. Navarra +2

Using the QCD sum rule approach we investigate the possible four-quark structure of the recently observed charmed scalar mesons $D_{0}^{0} (2308)$ (BELLE) and $D_{0}^{0, +} (2405)$ (FOCUS…

Pentaquark Decay Width in QCD Sum Rules

M. Eidemüller, F. S. Navarra, M. Nielsen +1

In a diquark-diquark-antiquark picture of the pentaquark we study the decay $Θ \to K^{+} n$ within the framework of QCD sum rules. After evaluation of the relevant three-poi…
