Is the newly reported $X(5568)$ a $B\bar{K}$ molecular state?

Abstract

In this work, we perform a dynamical study of the $B^{(\ast )}$ and $\bar{K}$ interaction and show that the newly reported $X(5568)$ or $X(5616)$ cannot be assigned to be an isovector $B\bar{K}$ or $B^{\ast }\bar{K}$ molecular state. We continue to investigate the isoscalar $B^{(\ast )}\bar{K}$ systems, and the $B^{(\ast )}\bar{K}$ systems with isospin $I=0,1$, and predict the existence of several isoscalar $B^{(\ast )}{\bar{K}}^{(\ast )}$ molecular states. A new task of exploring open-bottom molecular states will be created for future experiments.
