QCD equation of state and the structure of neutron stars in NJL model
Shu-Sheng Xu
The chiral and pion superfluidity phase transitions are studied within NJL model. The model parameters are fitted by pion mass and decay constant together with recent isospin densi…
Pseudoscalar glueball mass: a window on three-gluon interactions
E. V. Souza, M. N. Ferreira, A. C. Aguilar +3
In pure-glue QCD, gluon-gluon scattering in the channel is described by a very simple equation, especially if one considers just the leading contribution to the sca…
Masses of ground-state mesons and baryons, including those with heavy quarks
Pei-Lin Yin, Chen Chen, Gastao Krein +3
Using a confining, symmetry-preserving regularisation of a vectorvector contact interaction, we compute the spectra of ground-state pseudoscalar and vector meso…
New Perspective on Hybrid Mesons
Shu-Sheng Xu, Zhu-Fang Cui, Lei Chang +3
It is thought that strong interactions within the Standard Model can generate bound-states in which non-Abelian gauge-bosons play a dual role, serving both as force and matter fiel…
Pion and kaon valence-quark quasiparton distributions
Shu-Sheng Xu, Lei Chang, Craig D. Roberts +1
Algebraic Ansaetze for the Poincaré-covariant Bethe-Salpeter wave functions of the pion and kaon are used to calculate their light-front wave functions (LFWFs), parton distribution…
Parity partners in the baryon resonance spectrum
Ya Lu, Chen Chen, Craig D. Roberts +3
We describe a calculation of the spectrum of flavour-SU(3) octet and decuplet baryons, their parity partners, and the radial excitations of these systems, made using a symmetry-pre…
Critical endpoint in the presence of a chiral chemical potential
Zhu-Fang Cui, Ian C. Cloet, Ya Lu +4
A class of Polyakov-loop-modified Nambu--Jona-Lasinio (PNJL) models have been used to support a conjecture that numerical simulations of lattice-regularized quantum chromodynamics…
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…
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…
