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

Abstract

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 $D_s{\bar{D}}_{s0}(2317)+h.c.$ molecular current with $J^{PC}=0^{-+}$. We consider the contributions of condensates up to dimension ten and we work at leading order in ${\alpha }_s$. We keep terms which are linear in the strange quark mass $m_s$. The mass obtained for such state is $m_{D_s{D}_{s0}}=(4.80\pm 0.55)$ GeV. We also consider a molecular $0^{-+}$ $D{\bar{D}}_0(2400)+h.c.$ current and we obtain $m_{D{D}_0}=(4.61\pm 0.71)$ GeV. Our study shows that the newly observed Y(4274) in the $J/\psi \varphi$ invariant mass spectra can be, considering the uncertainties, described using a molecular charmonium current.
