“…It is remarkable that the three-bodyKπΞ channel contributes sizable width to Ωð2012Þ in the S-wave hadronic molecule scenario, while it has difficulty happening in the compact decuplet baryon assignment. Inspired by this significant difference, the Belle Collaboration tried to distinguish these two interpretations of Ωð2012Þ by searching for its three-body decay toKπΞ [23]. They did not observe the significant Ωð2012Þ signals in theKπΞ channel and drew their conclusion with the 90% credibility level upper limits on the ratios of the branching fractions of three-bodyKπΞ toKΞ two-body decay, BðΩð2012Þ →KπΞÞ=BðΩð2012Þ →KΞÞ < 11.9%.…”

After the recent discovery of the new Ω Ã state, the ratio of the branching fractions of Ωð2012Þ →KπΞ relative to theKΞ decay channel was investigated by the Belle Collaboration. The measured 11.9% upper limit to this ratio is in sharp tension with the S-waveKΞð1530Þ molecule interpretation for Ωð2012Þ, which indicates the dominantKπΞ three-body decay. We try to explore the possibility of the P-wave molecule assignments for Ωð2012Þ [where Ωð2012Þ has positive parity]. It is found that the latest experimental measurements are compatible with the 1=2 þ and 3=2 þK Ξð1530Þ molecular pictures, while the 5=2 þ KΞð1530Þ molecule shows largerKπΞ three-body decay thanKΞ decay as in the case of an S-wave molecule. Thus, the newly observed Ωð2012Þ can be interpreted as the 1=2 þ or 3=2 þK Ξð1530Þ molecule state according to current experiment data.

“…[23][24][25][26][27][28]. However, the large decay width for Ωð2012Þ →KΞ Ã →KπΞ, predicted by the molecular nature [23][24][25], is in disagreement with the very recent Belle measurement [29]. The measured ratio of the three body decay width to the one of the two body decay, RK πΞ KΞ ¼ Γ Ωð2012Þ→KπΞ =Γ Ωð2012Þ→KΞ , is less than 11.9% at the 90% confidence level [29].…”

We report on a theoretical study of the newly observed Ωð2012Þ resonance in the nonleptonic weak decays of Ω 0 c → π þK Ξ Ã ð1530ÞðηΩÞ → π þ ðKΞÞ − and π þ ðKΞπÞ − via final-state interactions of thē KΞ Ã ð1530Þ and ηΩ pairs. The weak interaction part is assumed to be dominated by the charm quark decay process: cðssÞ → ðs þ u þdÞðssÞ, while the hadronization part takes place between the sss cluster from the weak decay and a quark-antiquark pair with the quantum numbers J PC ¼ 0 þþ of the vacuum, producing a pair ofKΞ Ã ð1530Þ and ηΩ. Accordingly, the finalKΞ Ã ð1530Þ and ηΩ states are in pure isospin I ¼ 0 combinations, and the Ω 0 c → π þK Ξ Ã ð1530ÞðηΩÞ → π þ ðKΞÞ − decay is an ideal process to study the Ωð2012Þ resonance. With the final-state interaction described in the chiral unitary approach, up to an arbitrary normalization, the invariant mass distributions of the final states are calculated, assuming that the Ωð2012Þ resonance with spin-parity J P ¼ 3=2 − is dynamically generated from the coupled channels interactions of theKΞ Ã ð1530Þ and ηΩ in s-wave andKΞ in d-wave. We also calculate the ratio RK Ξπ KΞ ¼ Br½Ω 0 c → π þ Ωð2012Þ − → π þ ðKΞπÞ − =Br½Ω 0 c → π þ Ωð2012Þ − → π þ ðKΞÞ −. The proposed mechanism can provide valuable information on the nature of the Ωð2012Þ and can in principle be tested by future experiments, such as LHCb, Belle, BelleII, and the planed facilities, such as the super tau charm facility and electron ion collider at China.

Is the exotic 0−− glueball a pure gluon state?

We present a new calculation of the mass and width of the exotic 0 −− glueball in the framework of the QCD sum rules. We next construct a new current which couples to a pure 0 −− gluon state and derive consistent and stable sum rules. A previously used current in this approach was shown to be inconsistent. We obtain for this state a mass MG = 6.3 +0.8 −1.1 GeV and an upper limit for the total width ΓG ≤ 235 MeV. These values can be used as an important guide for the experimental search of this exotic state. We argue that the mixing of this glueball state with 0 −− tetraquark is very small. Therefore, the exotic 0 −− glueball can be considered as a pure gluon state.
