Can the X(4350) narrow structure be a \(1^{-+}\) exotic state?

Using the QCD sum rules we test if the new narrow structure, the X(4350) recently observed by the Belle Collaboration, can be described as a \(J^{PC}=1^{-+}\) exotic \(D_s^*D_{s0}^*\) molecular state. We consider the contributions of condensates up to dimension eight, we work at leading order in \(\...

Description
Summary:Using the QCD sum rules we test if the new narrow structure, the X(4350) recently observed by the Belle Collaboration, can be described as a \(J^{PC}=1^{-+}\) exotic \(D_s^*D_{s0}^*\) molecular state. We consider the contributions of condensates up to dimension eight, we work at leading order in \(\alpha_s\) and we keep terms which are linear in the strange quark mass \(m_s\). The mass obtained for such state is \(m_{D_s^*{D}_{s0}^*}=(5.05\pm 0.19)\) GeV. We also consider a molecular \(1^{-+}, D^{*}{D}_0^{*}\) current and we obtain \(m_{D^*{D}_0^*}=(4.92\pm 0.08)\) GeV. We conclude that it is not possible to describe the X(4350) structure as a \(1^{-+} D_s^*{D}_{s0}^*\) molecular state.
