Improved automated lattice perturbation theory in background field gauge
Improved automated lattice perturbation theory background field gauge
2011/1/6
We present an algorithm to automatically derive Feynman rules for lattice perturbation theory in background field gauge. Vertices with an arbitrary number of both background and quantum legs can be de...
