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…
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…
