Deconfinement at finite chemical potential
A. Bender, G. I. Poulis, C. D. Roberts +2
In a confining, renormalisable, Dyson-Schwinger equation model of two-flavour QCD we explore the chemical-potential dependence of the dressed-quark propagator, which provides a mea…
Leptonic and semileptonic decays of heavy mesons
C. D. Roberts, M. A. Ivanov, Yu. L. Kalinovsky +1
A heavy-quark limit of the Dyson-Schwinger equations is introduced and used in an exploratory study of leptonic and semileptonic decays of heavy mesons. The application of this fra…
Differences between heavy and light quarks
P. Maris, C. D. Roberts
The quark Dyson-Schwinger equation shows that there are distinct differences between light and heavy quarks. The dynamical mass function of the light quarks is characterised by a s…
pi- and K-meson Bethe-Salpeter Amplitudes
P. Maris, C. D. Roberts
Independent of assumptions about the form of the quark-quark scattering kernel, K, we derive the explicit relation between the flavour-nonsinglet pseudoscalar meson Bethe-Salpeter…
