The parton distribution function of the pion in the valence region is extracted in a next-to-leading order analysis from Fermilab E-615 pionic Drell-Yan data. The effects of the parametrization of the pion's valence distributions are examined. Modern nucleon parton distributions and nuclear corrections were used and possible effects from higher twist contributions were considered in the analysis. In the next-to-leading order analysis, the high-x dependence of the pion structure function differs from that of the leading order analysis, but not enough to agree with the expectations of pQCD and Dyson-Schwinger calculations.read more

TL;DR: In this article, the authors survey contemporary studies of hadrons and strongly interacting quarks using QCD's Dyson-Schwinger equations, addressing aspects of confinement and dynamical chiral symmetry breaking; the hadron spectrum; hadron elastic and transition form factors, from small-to large-Q^2; parton distribution functions; the physics of having one or more heavy quarks; and properties of the quark gluon plasma.

TL;DR: The last five years have brought considerable progress in the study of the bound-state problem in continuum quantum field theory as discussed by the authors, and it appears possible that the next five years will bring profound growth in our store of knowledge about hadrons and nuclei.

TL;DR: A survey of contemporary studies of hadrons and strongly interacting quarks using QCD's DysonSchwinger equations is given in this paper, 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 having one or more heavy quarks; and properties of the quark gluon plasma.

Pion electromagnetic form factor at spacelike momenta.
TL;DR: The analysis shows that hard contributions to the pion form factor dominate for Q²≳8 GeV², but, even so, the magnitude of Q²F(π)(Q²) reflects the scale of dynamical chiral symmetry breaking, a pivotal emergent phenomenon in the standard model.
