Possible $B^{(\ast )}\bar{K}$ hadronic molecule state

Abstract

In the present work, we estimate the decays of the $X(5568)$ and $X(5616)$ in a $B\bar{K}$ and a $B^{\ast }\bar{K}$ $S$-wave hadronic molecule scenarios, respectively, which may corresponding to the structure observed by D0 Collaboration. Our estimation indicates both $B\bar{K}$ and $B^{\ast }\bar{K}$ hadronic molecule decay widths could explain the experimental data in a proper model parameter range.
