Charmonium-like states with the exotic quantum number
Hong-Zhou Xi, Hua-Xing Chen, Wei Chen +3
We apply the method of QCD sum rules to study the tetraquark states with the exotic quantum number , and extract the mass of the lowest-lying s…
Radiative decays of -wave bottom baryons from light-cone sum rules
Xuan Luo, Hui-Min Yang, Hua-Xing Chen
We carry out a comprehensive investigation on the radiative decays of -wave bottom baryons using the light-cone sum rule method. We analyze their electromagnetic transitions int…
Hadronic molecules with four charm or beauty quarks
Wen-Ying Liu, Hua-Xing Chen
We apply the extended local hidden gauge formalism to study the meson-meson interactions with the quark constituents , , $cc\bar b\b…
Investigation on the from QCD sum rules
Niu Su, Hua-Xing Chen, Philipp Gubler +1
We study the recently observed baryon in QCD sum rules. We construct the -wave baryon currents with a covariant derivative, and perform spin projection to obtain t…
Light single-gluon hybrid states with various (exotic) quantum numbers
Wei-Han Tan, Niu Su, Hua-Xing Chen
We apply the QCD sum rule method to study the light single-gluon hybrid states with various (exotic) quantum numbers. We construct twenty-four single-gluon hybrid currents, and use…
Revisit the heavy quarkonium double-gluon hybrid mesons with exotic quantum numbers
Ding-Kun Lian, Qi-Nan Wang, Xu-Liang Chen +3
We revisit the masses of heavy quarkonium double-gluon hybrid mesons with exotic quantum numbers and in the framework of the QCD sum rules. Considering the…
