Abstract

We use QCD sum rules to study the possible existence of a D _sD̄* -D_s*D̄ molecule with the quantum number J^PC = 1⁺⁺. We consider the contributions of condensates up to dimension eight and work at leading order in α_s. We obtain mD_sD* = (3.96 ± 0.10) GeVaround 100 MeV above the mass of the meson X(3872). The proposed state is a natural generalized state to the strangeness sector of the X(3872), which was also found to be consistent with a multiquark state from a previous QCD sum rule analysis.
