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…
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…
