Bottom Baryons
Xiang Liu, Hua-Xing Chen, Yan-Rui Liu +2
Recently CDF and D0 collaborations observed several bottom baryons. In this work we perform a systematic study of the masses of bottom baryons up to in the framework of hea…
Light Scalar Mesons in the QCD Sum Rule
Hua-Xing Chen, Atsushi Hosaka, Shi-Lin Zhu
We study the light scalar mesons in the QCD sum rule. We find that there are five independent scalar tetraquark currents in the local form, and we perform QCD sum rule analysis usi…
Light Scalar Tetraquark Mesons in the QCD Sum Rule
Hua-Xing Chen, Atsushi Hosaka, Shi-Lin Zhu
We study the lowest-lying scalar mesons in the QCD sum rule by considering them as tetraquark states. We find that there are five independent currents for each state with a certain…
