Vacuum Polarization and Dynamical Chiral Symmetry Breaking: Phase Diagram of QED with Four-Fermion Contact Interaction
F. Akram, A. Bashir, L. X. Gutierrez-Guerrero +4
We study chiral symmetry breaking for fundamental charged fermions coupled electromagnetically to photons with the inclusion of four-fermion contact self-interaction term. We emplo…
Quark flavour effects on gluon and ghost propagators
A. Ayala, A. Bashir, D. Binosi +2
We compute the full non-perturbative ghost and gluon two-point Green functions by using gauge field configurations with $\nf=2$ and $\nf=2+1+1$ twisted-mass quark flavours. We use…
Collective perspective on advances in Dyson-Schwinger Equation QCD
Adnan Bashir, Lei Chang, Ian C. Cloet +4
We survey contemporary studies of hadrons and strongly interacting quarks using QCD's Dyson-Schwinger equations, addressing: aspects of confinement and dynamical chiral symmetry br…
