Radiative decay of Ξb(6227) in a hadronic molecule picture

The baryon Xi(b)(6227) with the quantum number J(P) = 1/2(-) is considered as a molecular state composed of a Sigma(b) baryon and (K) over bar meson. The partial decay widths of the Sigma(b)(K) over bar molecular state into Xi(b)gamma and Xi'(b)gamma final states through hadronic loops are evaluated with the help of the effective Lagrangians. The partial widths for the Xi(b)(6227) -> gamma Xi(b) and Xi(b)(6227) -> gamma Xi'(b) transitions are evaluated at 1.50-1.02 keV and 17.56-24.91 keV, respectively, which may be accessible for the LHCb. Based on our results, we argue that an experimental determination of the radiative decay width of Xi(b)(6227) is important for the understanding of its intrinsic properties.
