Query: Y(4626) as a molecular state from interaction
  ${D}^*_s\bar{D}_{s1}(2536)-{D}_s\bar{D}_{s1}(2536)$   Recently, a new structure $Y(4626)$ was reported by the Belle Colloboration
in the process $e^+e^-\to D_s^+D_{s1}(2536)^-$. In this work, we propose an
assignment of the $Y(4626)$ as a ${D}^*_s\bar{D}_{s1}(2536)$ molecular state,
which decays into the $D_s^+D_{s1}(2536)^-$ channel through a coupling between
${D}^*_s\bar{D}_{s1}(2536)$ and ${D}_s\bar{D}_{s1}(2536)$ channels. With the
help of the heavy quark symmetry, the potential of the interaction
${D}^*_s\bar{D}_{s1}(2536)-{D}_s\bar{D}_{s1}(2536)$ is constructed within the
one-boson-exchange model, and inserted into the quasipotential Bethe-Salpeter
equation. The pole of obtained scattering amplitude is searched for in the
complex plane, which corresponds to a molecular state from the interaction
${D}^*_s\bar{D}_{s1}(2536)-{D}_s\bar{D}_{s1}(2536)$. The results suggest that a
pole is produced near the ${D}^*_s\bar{D}_{s1}(2536)$ threshold, which exhibits
as a peak in the invariant mass spectrum of the ${D}_s\bar{D}_{s1}(2536)$
channel at about 4626 MeV. It obviously favors the $Y(4265)$ as a
${D}^*_s\bar{D}_{s1}(2536)$ molecular state. In the same model, other molecular
states from the interaction ${D}^*_s\bar{D}_{s1}(2536)-{D}_s\bar{D}_{s1}(2536)$
are also predicted, which can be checked in future experiments.
