Width of the exotic $X_b(5568)$ state through its strong decay to $B_s^0{\pi }^{+}$

Abstract

The width of the newly observed exotic state $X_b(5568)$ is calculated via its dominant strong decay to using the QCD sum rule method on the light-cone in conjunction with the soft-meson approximation. To this end, the vertex $X_b{B}_s\pi$ is studied and the strong coupling $g_{X_b{B}_s\pi }$ is computed employing for $X_b(5568)$ state the interpolating diquark-antidiquark current of the $[su][\overline{b}\overline{d}]$ type. The obtained prediction for the decay width of $X_b(5568)$ is confronted and a nice agreement found with the experimental data of the D0 Collaboration.
