Abstract

The baryon with the quantum number is considered as a molecular state composed of a baryon and meson. The partial decay widths of the molecular state into and final states through hadronic loops are evaluated with the help of the effective Lagrangians. The partial widths for the and 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 is important for the understanding of its intrinsic properties.
