Another look at the Landau-gauge gluon and ghost propagators at low momentum
Andre Sternbeck, Michael Müller-Preussker
We study the gluon and ghost propagators of SU(2) lattice Landau gauge theory and find their low-momentum behavior being sensitive to the lowest non-trivial eigenvalue (λ_1) of the…
