Heavy and Light Pentaquark Chiral Lagrangian
Y. -R. Liu, A. Zhang, P. -Z. Huang +3
Using the SU(3) flavor symmetry, we construct the chiral Lagrangians for the light and heavy pentaquarks. The correction from the nonzero quark is taken into account perturbatively…
Pentaquarks in Jaffe and Wilczek's Diquark Model
A. Zhang, Y. -R. Liu, P. -Z. Huang +3
If Jaffe and Wilczek's diquark picture for pentaquark is correct, there should also exist a (3) pentaquark octet and singlet with no orbital excitation between the diqu…
D_s(2317) and D_s(2457) from HQET Sum Rules
Yuan-Ben Dai, Chao-Shang Huang, Chun Liu +1
Within the framework of the heavy quark effective theory, QCD sum rules are used to calculate the masses of p-wave (c-bar s) states. The results for 0^+ and 1^+ states with the ang…
Magnetic Moments of Pentaquarks
W. -W. Li, Y. -R. Liu, P. -Z. Huang +3
If the of and pentaquarks is really found to be by future experiments, they will be accompanied by partners in some model…
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…
An improvement on RPA based on a Boson mapping
Shi-Lin Zhu, Zhi-ning Zhou, Ze-sen Yang
We use a solvable model to perform modified dyson mapping and reveal the unphysical-state effects in the original Random Phase Approximation (RPA). We then propose a method to intr…
