@article{Bashir2012CollectivePO, title={Collective Perspective on Advances in Dyson—Schwinger Equation QCD}, author={Adnan Bashir and Lei Chang and Ian C.

We survey contemporary studies of hadrons and strongly interacting quarks using QCD's Dyson—Schwinger equations, addressing the following aspects: confinement and dynamical chiral symmetry breaking; the hadron spectrum; hadron elastic and transition form factors, from small- to large-Q2; parton distribution functions; the physics of hadrons containing one or more heavy quarks; and properties of the quark gluon plasma.
