Impact of Dynamical Fermions on QCD Vacuum Structure [PDF]

open access: yes, 2008
We examine how dynamical fermions affect both the UV and infrared structure of the QCD vacuum. We consider large $28^3 \times 96$ lattices from the MILC collaboration, using a gluonic definition of the topological charge density, founded on a new over ...
