Pentaquark Magnetic Moments In Different Models
Y. -R. Liu, P. -Z. Huang, W. -Z. Deng +2
We calculate the magnetic moments of the pentaquark states from different models and compare our results with predictions of other groups.
Meson Mass Formula from Random Phase Approximation
Weizhen Deng, Xiaolin Chen, Dahai Lu +1
We present a meson mass formula from random phase approximation (RPA). Both the mesons of ground-state pseudoscalar octet and the ground-state vector octet are described…
Understanding Pentaquark States in QCD
Shi-Lin Zhu
We estimate the mass of the pentaquark state with QCD sum rules and find that pentaquark states with isospin lie close to each other around GeV. The ex…
Understanding the and with Sum Rules in HQET
Yuan-Ben Dai, Chao-Shang Huang, Chun Liu +1
In the framework of heavy quark effective theory we use QCD sum rules to calculate the masses of the and excited states. The results are consis…
Chiral Symmetry in an Extended Constituent Quark Potential Model
Weizhen Deng, Yanrui Liu, Xiaolin Chen +2
The chiral symmetry is applied to an extended constituent quark potential model. With random phase approximation (RPA), the model comprises sea quark excitations. To obtain the pse…
