$D_s{D}^{\ast }$ molecule as an axial meson

Abstract

We use QCD sum rules to study the possible existence of a $D_s{\bar{D}}^{\ast }+D_s^{\ast }\bar{D}$ molecule with the quantum number $J^P=1^{+}$. We consider the contributions of condensates up to dimension eight and work at leading order in ${\alpha }_s$. We obtain $m_{D_sD^*}=(3.96\pm0.10) \GeV$ around 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.
