AB  - 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 C = 1, S = -2, and I = 0 sector, where five Omega((*))(c) 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 Lambda(c)(2595) and Lambda(c)(2625), and Lambda(b)(5912) and Lambda(b)(5920) resonances. We show that some (probably at least three) of the states observed by LHCb will also have odd parity and J = 1/2 or J = 3/2, belonging two of them to the same SU(6)(light-spin-flavor) x HQSS multiplets as the latter charmed and beauty Lambda baryons.
