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…
Predictions of masses for light hybrid baryons
Qi-Nan Wang, Ding-Kun Lian, Wei Chen +4
Within the method of parity-projected QCD sum rules, we study the mass spectra of light hybrid baryons with $I(J^{P})=1/2(1/2^{\pm}), 3/2(1/2^{\pm}), 1/2(3/2^{\pm}), 3/2(3/2^{\pm})…
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…
Light hybrid baryons in QCD sum rules
Wei Chen, Qi-Nan Wang, Ding-Kun Lian +4
We have calculated the mass spectra of nucleon and delta hybrid baryons with both positive-parity and negative-parity by using the method of QCD sum rules. We predicte that the low…
