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…
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…
Topped baryons from QCD sum rules
Shu-Wei Zhang, Wei-Han Tan, Xuan Luo +1
The recent CMS observation of a near-threshold enhancement in top quark pair production provides the first experimental indication of a short-lived pseudoscalar bound st…
Radiative decays of -wave charmed baryons in the flavor representation
Xuan Luo, Hua-Xing Chen, Er-Liang Cui +3
We perform a comprehensive investigation of the radiative decays of -wave charmed baryons in the flavor representation, employing the light-cone QCD sum r…
