The decay properties of two- and three- gluon glueballs
Wei-Han Tan, Hua-Xing Chen, Ding-Kun Lian +1
We previously studied the decay properties of two- and three-gluon glueballs using the Fierz rearrangement method and obtained their relative branching ratios in Ref.~\cite{Tan:202…
Quantum numbers of excited and baryons and the -wave spectrum
Xuan Luo, Shu-Wei Zhang, Hua-Xing Chen +1
Recent precision measurements of excited heavy baryons, combined with systematic theoretical studies, make it possible to resolve the fine structure of their spectra. We calculate…
Light tetraquark states with from QCD sum rules
Yi-Wei Jiang, Hua-Xing Chen, Er-Liang Cui +3
We perform a systematic QCD sum rule study of light tetraquark states with in the diquark--antidiquark picture. A complete set of local interpolating currents is co…
Investigating charmed hybrid baryons via QCD sum rules
Hui-Min Yang, Xuan Luo, Hua-Xing Chen +1
We investigate charmed hybrid baryons using the QCD sum rule method within the framework of heavy quark effective theory. We construct twenty-eight interpolating currents for charm…
A short review on QCD sum rule studies of P-wave single heavy baryons
Xuan Luo, Shu-Wei Zhang, Hua-Xing Chen +3
Over the past few decades, the study of singly heavy baryons has entered a golden era, with numerous excited states observed by experimental collaborations. Various theoretical app…
QCD sum rule study of topped mesons within heavy quark effective theory
Shu-Wei Zhang, Xuan Luo, Hui-Min Yang +1
Motivated by the recent CMS observation of a near-threshold enhancement in top quark pair production, we investigate a novel class of hadronic systems containing a single top quark…
