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…
Improved prediction of the mass splitting for -wave baryons
Niu Su, Hua-Xing Chen, Philipp Gubler +1
Using the QCD sum rule method, we investigate the mass splitting for the spin-orbit partner states of the baryon assuming that it is a -wave excitation with $J^P=3/2^-…
Investigation on the from QCD sum rules
Niu Su, Hua-Xing Chen, Philipp Gubler +1
We investigate the recently observed baryon using QCD sum rules. By constructing -wave baryon currents and performing spin projection and parity projection, we obt…
A study of the correlation function
Luciano M. Abreu, Philipp Gubler, K. P. Khemchandani +2
The femtoscopic correlation function is studied within a hadronic effective Lagrangian approach with coupled channels, based on hidden local symmetry. The results are compared…
The impact of quark many-body effects on exotic hadrons
Sachiko Takeuchi, Makoto Takizawa, Yasuhiro Yamaguchi +1
We investigate the exotic hadrons consisting of two light quarks and two heavy antiquarks, -. The spin-dependent term between quarks is known to give an attra…
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…
