Discriminating baryonium and final-state-interaction interpretations of
Bing-Dong Wan, Sheng-Qi Zhang
We revisit the enhancement observed by BESIII in from the viewpoint of near-threshold dynamics. Motivated by the possibility of light baryoniu…
Decipher the nature of glueball candidate
Sheng-Qi Zhang, Bing-Dong Wan, Cong-Feng Qiao
As a unique form of matter composed entirely of gauge bosons, glueballs are an important low-energy prediction of QCD. After decades of searches, the BESIII Collaboration recently…
Nodal mechanism for the suppressed decay of in the Bethe--Salpeter framework
Bing-Dong Wan, Sheng-Qi Zhang
The strong decay is anomalously suppressed despite ample phase space, whereas the and channels remain sizable. In this work, we study…
Baryons and baryoniums in the perspective of QCD sum rules
Sheng-Qi Zhang, Cong-Feng Qiao
Following the experimental confirmation of tetraquark and pentaquark states, the search for hexaquark states has emerged as a new frontier in hadron physics. The recent observation…
Strange pentaquark molecules in QCD sum rules
Di Ben, Sheng-Qi Zhang
We study hidden- and open-strange pentaquark configurations in the hadronic molecular picture with QCD sum rules. Starting from the baryon octet combined with an pair, w…
Spectrum of Light Hexaquark States in Triquark-antitriquark Configuration
Xuan-Heng Zhang, Sheng-Qi Zhang, Cong-Feng Qiao
To understand the nature of and observed by the BESIII collaboration in the system, we systematically investigate the possibility that these states are…
Rare decays and new physics effects
Sheng-Qi Zhang, Cong-Feng Qiao
Recent experimental progress on baryonic rare decays has spurred a deeper investigation on flavor-changing neutral current transitions in the baryon sector. Within the framework of…
The Spectra of and Hexaquark States
Xuan-Heng Zhang, Sheng-Qi Zhang, Cong-Feng Qiao
Motivated by the observation of the resonance in the system by the BESIII collaboration, we studied the molecular states of hexaquarks and $…
Hyperon semileptonic decays in QCD sum rules
Sheng-Qi Zhang, Xuan-Heng Zhang, Cong-Feng Qiao
We investigate the hyperon semileptonic decays within the framework of QCD sum rules. The flavor symmetry breaking effects are analyzed via the relevant form factors and…
Gluonic nature of the newly observed state
Sheng-Qi Zhang, Bing-Dong Wan, Liang Tang +1
Motivated by the newly observed resonance by BESIII Collaboration, we examine the trigluon glueball interpretation for it in the framework of QCD sum rules. We evaluate t…
Possible structure of the newly found exotic state
Bing-Dong Wan, Sheng-Qi Zhang, Cong-Feng Qiao
Recently, a hadronic state named , about 1.86 GeV, was observed in the BESIII experiment. This finding has a peculiar interest due to its exotic quantum number $J^{PC}=1…
Light baryonium spectrum
Bing-Dong Wan, Sheng-Qi Zhang, Cong-Feng Qiao
We evaluate the light baryonium spectrum, viz. the baryon-antibaryon states, in the framework of QCD sum rules. The nonperturbative contributions up to dimension 12 are taken into…
