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…
Cold quarks in medium: an equation of state
Thomas Klahn, Craig D. Roberts, Lei Chang +2
We derive a compact, semi-algebraic expression for the cold quark matter equation of state (EoS) in a covariant model that exhibits coincident deconfinement and chiral symmetry res…
Exploring the light-quark interaction
Lei Chang, Ian C. Cloet, Bruno El-Bennich +2
Two basic motivations for an upgraded JLab facility are the needs: to determine the essential nature of light-quark confinement and dynamical chiral symmetry breaking (DCSB); and t…
Gauge invariance of a critical number of flavours in QED3
A. Bashir, A. Raya, S. Sanchez-Madrigal +1
The fermion propagator in an arbitrary covariant gauge can be obtained from the Landau gauge result via a Landau-Khalatnikov-Fradkin transformation. This transformation can be writ…
Neutron Stars and the High Density Equation of State
T. Klahn, C. D. Roberts, D. B. Blaschke +1
One of the key ingredients to understand the properties of neutrons stars is the equation of state at finite densities far beyond nuclear saturation. Investigating the phase struct…
Sketching the Bethe-Salpeter kernel
Lei Chang, Craig D. Roberts
An exact form is presented for the axial-vector Bethe-Salpeter equation, which is valid when the quark-gluon vertex is fully dressed. A Ward-Takahashi identity for the Bethe-Salpet…
