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…
Dynamical Schwinger effect and high-intensity lasers. Realising nonperturbative QED
D. B. Blaschke, A. V. Prozorkevich, G. Roepke +4
We consider the possibility of experimental verification of vacuum e^+e^- pair creation at the focus of two counter-propagating optical laser beams with intensities 10^{20}-10^{22}…
Form Factors and Dyson-Schwinger Equations
I. C. Cloet, C. D. Roberts
A synopsis exemplifying the employment of Dyson-Schwinger equations in the calculation and explanation of hadron electromagnetic form factors and related phenomena. In particular t…
Chemical potential and the gap equation
Huan Chen, Wei Yuan, Lei Chang +3
In general the kernel of QCD's gap equation possesses a domain of analyticity upon which the equation's solution at nonzero chemical potential is simply obtained from the in-vacuum…
Regarding confinement and dynamical chiral symmetry breaking in QED3
A. Bashir, A. Raya, I. C. Cloet +1
We establish that QED3 can possess a critical number of flavours, N_f^c, associated with dynamical chiral symmetry breaking if, and only if, the fermion wave function renormalisati…
Current quark mass dependence of nucleon magnetic moments and radii
I. C. Cloet, G. Eichmann, V. V. Flambaum +3
A calculation of the current-quark-mass-dependence of nucleon static electromagnetic properties is necessary in order to use observational data as a means to place constraints on t…
Perspective on rainbow-ladder truncation
G. Eichmann, R. Alkofer, I. C. Cloet +2
Prima facie the systematic implementation of corrections to the rainbow-ladder truncation of QCD's Dyson-Schwinger equations will uniformly reduce in magnitude those calculated mas…
Aspects of Hadron Physics
C. D. Roberts, M. S. Bhagwat, S. V. Wright +1
Detailed investigations of the structure of hadrons are essential for understanding how matter is constructed from the quarks and gluons of Quantum chromodynamics (QCD), and amongs…
