Description of the ${\Xi }_c$ and ${\Xi }_b$ states as molecular states

Abstract

In this work we study several ${\Xi }_c$ and ${\Xi }_b$ states dynamically generated from the meson-baryon interaction in coupled channels, using an extension of the local hidden gauge approach in the Bethe-Salpeter equation. These molecular states appear as poles of the scattering amplitudes, and several of them can be identified with the experimentally observed ${\Xi }_c$ states, including the ${\Xi }_c(2790)$, ${\Xi }_c(2930)$, ${\Xi }_c(2970)$, ${\Xi }_c(3055)$ and ${\Xi }_c(3080)$. Also, for the recently reported ${\Xi }_b(6227)$ state, we find two poles with masses and widths remarkably close to the experimental data, for both the $J^P=1/2^{-}$ and $J^P=3/2^{-}$ sectors.
