QCD sum rule calculation for the charmonium-like structures in the J/psi phi and J/psi omega invariant mass spectra

Stefano I. Finazzo, Xiang Liu, Marina Nielsen

Using the QCD sum rules we test if the charmonium-like structure Y(4274), observed in the $J/\psi \varphi$ invariant mass spectrum, can be described with a $D_s{\bar{D}}_{s0}(2317)+h.c.$ molec…
