Figure 1

The new SDE for the gluon-ghost system. Wavy lines with white blobs are full gluon propagators, dashed lines with white blobs are full-ghost propagators, black blobs are full vertices, and the gray blob denotes the scattering kernel. The circles attached to the external gluons denote that, from the point of view of Feynman rules, they are treated as background fields.Reuse & Permissions

Figure 2

Left panel: The gluon propagator obtained from the solution of the SDE system (blue continuous line) compared to the lattice data of 7; the red dashed line represents the perturbative behavior. In the inset we show the function $1+G(q^2)$ (blue continuous line) and its perturbative behavior (red dashed line). Right panel: The ghost propagator obtained from the SDE system (blue continuous line), the one-loop perturbative result (red dashed line), and the corresponding lattice data of 7. In the inset we show the function $p^{2}D(p^2)$ from the SDE.Reuse & Permissions
