Discussion for the Solutions of Dyson-Schwinger Equations at m>0 in QED3
Hui-xia Zhu, Hong-tao Feng, Wei-min Sun +1
In the case of nonzero fermion mass, within a range of Ansatze for the full fermion-boson vertex, we show that Dyson-Schwinger equation for the fermion propagator in QED3 has two q…
Vacuum pseudoscalar susceptibility
Lei Chang, Yu-Xin Liu, Craig D. Roberts +3
We derive a novel model-independent result for the pion susceptibility in QCD via the isovector-pseudoscalar vacuum polarisation. In the neighbourhood of the chiral-limit, the pion…
Chiral susceptibility and the scalar Ward identity
Lei Chang, Yu-xin Liu, Craig D. Roberts +3
The chiral susceptibility is given by the scalar vacuum polarisation at zero total momentum. This follows directly from the expression for the vacuum quark condensate so long as a…
The Calculation of and at Finite Chemical Potential
Yu Jiang, Yuan-mei Shi, Hua Li +2
Based on the previous work in [Y. Jiang, Y.M. Shi, H.T. Feng, W.M. Sun and H.S. Zong, Phys. Rev. C {\bf 78}, 025214 (2008)] on the quark-meson vertex and pion properties at finite…
The Chiral Quark Condensate and the Bag Constant with Finite Chemical Potential
Hong-shi Zong, Jia-lun Ping, Wei-min Sun +2
A method for obtaining the low chemical potential dependence of the dressed quark propagator from an effective quark-quark interaction model is developed. From this the chemical po…
