Higher topological charge and the QCD vacuum
It is shown that gauge field configurations with higher topological charge modify the structure of the QCD vacuum, which is reflected in its dependence on the CP-violating topological phase θ. To explore this, topological susceptibilities and the production of axion dark matter are studied here. The...
