Strong D* -> D+pi and B* -> B+pi couplings
Bruno El-Bennich, Mikhail A. Ivanov, Craig D. Roberts
We compute g_{D* D pi} and g_{B* B pi} using a framework in which all elements are constrained by Dyson-Schwinger equation studies of QCD, and therefore incorporates a consistent,…
Phase diagram and critical endpoint for strongly-interacting quarks
Si-xue Qin, Lei Chang, Huan Chen +2
We introduce a method based on the chiral susceptibility, which enables one to draw a phase diagram in the chemical-potential/temperature plane for strongly-interacting quarks whos…
Quark spectral density and a strongly-coupled QGP
Si-xue Qin, Lei Chang, Yu-xin Liu +1
The maximum entropy method is used to compute the dressed-quark spectral density from the self-consistent numerical solution of a rainbow truncation of QCD's gap equation at temper…
Dressed-quark anomalous magnetic moments
Lei Chang, Yu-Xin Liu, Craig D. Roberts
Perturbation theory predicts that a massless fermion cannot possess a measurable magnetic moment. We explain, however, that the nonperturbative phenomenon of dynamical chiral symme…
Essence of the vacuum quark condensate
Stanley J. Brodsky, Craig D. Roberts, Robert Shrock +1
We show that the chiral-limit vacuum quark condensate is qualitatively equivalent to the pseudoscalar meson leptonic decay constant in the sense that they are both obtained as the…
Empirically Charting Dynamical Chiral Symmetry Breaking
Lei Chang, Craig D. Roberts
We provide a snapshot of recent progress in hadron physics made using QCD's Dyson-Schwinger equations, reviewing the generation of a quark anomalous chromomagnetic moment, which ma…
Hadron Physics: The Essence of Matter
Lei Chang, Craig D. Roberts
Dynamical chiral symmetry breaking (DCSB) is a remarkably effective mass generating mechanism. It is also, amongst other things, the foundation for a successful application of chir…
Distribution Functions of the Nucleon and Pion in the Valence Region
Roy J. Holt, Craig D. Roberts
We provide an experimental and theoretical perspective on the behavior of unpolarized distribution functions for the nucleon and pion on the valence-quark domain; namely, Bjorken-x…
