Studies of two-solar-mass hybrid stars within the framework of Dyson-Schwinger equations
Tong Zhao, Shu-Sheng Xu, Yan Yan +3
In this paper we introduce an equation of state (EOS) of quark matter within the framework of Dyson-Schwinger equations (DSEs) to study the structure of compact stars. The smooth c…
Contact-interaction Faddeev equation and, inter alia, proton tensor charges
Shu-Sheng Xu, Chen Chen, Ian C. Cloet +3
A confining, symmetry-preserving, Dyson-Schwinger equation treatment of a vector-vector contact interaction is used to formulate Faddeev equations for the nucleon and Delta-baryon…
2+1 flavors QCD equation of state at zero temperature within Dyson-Schwinger equations
Shu-Sheng Xu, Yan Yan, Zhu-Fang Cui +1
Within the framework of Dyson-Schwinger equations (DSEs), we discuss the equation of state (EOS) and quark number densities of 2+1 flavors, that is to say, , , and quarks…
Susceptibilities and critical exponents within the Nambu--Jona-Lasinio model
Yi-Lun Du, Ya Lu, Shu-Sheng Xu +3
In the mean field approximation of (2+1)-flavor Nambu--Jona-Lasinio model, we strictly derive several sets of coupled equations for the chiral susceptibility, the quark number susc…
The chiral phase transition with a chiral chemical potential in the framework of Dyson-Schwinger equations
Shu-Sheng Xu, Zhu-Fang Cui, Bin Wang +3
Within the framework of Dyson-Schwinger equations (DSEs), we discuss the chiral phase transition of QCD with a chiral chemical potential as an additional scale. We focus espe…
Completing the picture of the Roper resonance
Jorge Segovia, Bruno El-Bennich, Eduardo Rojas +4
We employ a continuum approach to the three valence-quark bound-state problem in relativistic quantum field theory to predict a range of properties of the proton's radial excitatio…
