[Formula: see text] excited states within a [Formula: see text] HQSS model.

We have reviewed the renormalization procedure used in the unitarized coupled-channel model of Romanets et al. (Phys Rev D 85:114032, 2012), and its impact in the [Formula: see text], [Formula: see text], and [Formula: see text] sector, where five [Formula: see text] states have been recently observed by the LHCb Collaboration. The meson-baryon interactions used in the model are consistent with both chiral and heavy-quark spin symmetries, and lead to a successful description of the observed lowest-lying odd parity resonances [Formula: see text] and [Formula: see text], and [Formula: see text] and [Formula: see text] resonances. We show that some (probably at least three) of the states observed by LHCb will also have odd parity and [Formula: see text] or [Formula: see text], belonging two of them to the same [Formula: see text] HQSS multiplets as the latter charmed and beauty [Formula: see text] baryons.
