Can the X(4350) narrow structure be a 1−+ exotic state?
چکیده انگلیسی
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 JPC=1−+ exotic Ds∗Ds0∗ molecular state. We consider the contributions of condensates up to dimension eight, we work at leading order in αs and we keep terms which are linear in the strange quark mass ms. The mass obtained for such state is mDs∗Ds0∗=(5.05±0.19)GeV. We also consider a molecular 1−+, D∗D0∗ current and we obtain mD∗D0∗=(4.92±0.08)GeV. We conclude that it is not possible to describe the X(4350) structure as a 1−+Ds∗Ds0∗ molecular state.
