Odd-parity light baryon resonances

“…iii) The obtained states with J P Perhaps, the Σ(2250) resonance is of special relevance for our discussion here. It is classified with three stars, some experiments see two resonances, one of them with J P = 5 2 − and with a sizable ΞK decay mode [57]. Attending to this latter feature, we might assign the highest pole predicted by our model in Table XI to this Σ(2250) state.…”

“…Recently, the Belle Collaboration [1] announced the observation of Ξð1620Þ 0 in the Ξ − c π þ invariant mass spectrum of the Ξ þ c → Ξ − π þ π þ process, which confirmed early experimental evidence of Ξð1620Þ existing in the K − p reaction in the 1970s [2][3][4].

“…The reported mass, between 1600 and 1630 MeV/c 2 , seems to be too low for the second excited cascade resonance according to the constituent quark model [23]. Earlier evidence [24][25][26] has poor statistics. On the theoretical side, some dynamic models [27,28] have predicted a possible cascade resonance in the region of 1600 MeV/c 2 .…”
