Using the QCD sum rules we test if the charmonium-like structure Y(4274), observed in the J/ψϕ invariant mass spectrum, can be described with a DsD¯s0(2317)+h.c. molecular current with JPC=0−+. We consider the contributions of condensates up to dimension ten and we work at leading order in αs. We keep terms which are linear in the strange quark mass ms. The mass obtained for such state is mDsDs0=(4...
