Description
Many Ξc and Ξb resonances have been observed during past few of years. This works focus on studying several Ξc and Ξb dynamically generated states from meson-baryon interactions in coupled channels, using an extension of the local hidden gauge approach that we then unitarize using the Bethe-Salpeter equation. We are then able to identify several of our poles in the charm sector with some of the observed Ξc states [Ξc(2790), Ξc(2930), Ξc(2970), Ξc(3055) and Ξc(3080)], as well as two poles in the bottom sector that have masses and widths consistent with the newly observed Ξb(6227) resonance.
