$Z_{c} (3900)$ as a tetraquark state: decay width in QCD sum rules

J. M. Dias, F. S. Navarra, M. Nielsen +1

Supposing the $Z_{c}^{+} (3900)$ as a charged partner of the X(3872), we use the QCD sum rules techinques in order to obtain the coupling constants of the $Z_{c}^{+} J / ψ π^{+}$ …

CHARM 2013: X(4260) as a Mixed Charmonium-Tetraquark State

R. M. Albuquerque, J. M. Dias, M. Nielsen +1

Using the QCD sum rule approach we study the X(4260) state assuming that it can be described by a mixed charmonium-tetraquark current with $J^{P C} = 1^{--}$ quantum numbers. For the…

Predicition for the decay width of a charged state near the $D_{s} D ˉ^{} / D_{s}^{} D ˉ$ threshold

Jorgivan M. Dias, Xiang Liu, Marina Nielsen

Very recently it was predicted the existence of a charged state near the $D_{s} D ˉ^{*} / D_{s}^{*} D ˉ$ threshold. This state, that we call $Z_{cs}^{+}$ , would be the strange partner of…

$Z_{c}^{+} (3900)$ decay width in QCD sum rules

J. M. Dias, F. S. Navarra, M. Nielsen +1

We identify the recently observed charmonium-like structure $Z_{c}^{\pm} (3900)$ as the charged partner of the X(3872) state. Using standard techniques of QCD sum rules, we evaluate the…
