Large-order NSPT for lattice gauge theories with fermions: the plaquette in massless QCD

Abstract Numerical Stochastic Perturbation Theory (NSPT) allows for perturbative computations in quantum field theory. We present an implementation of NSPT that yields results for high orders in the perturbative expansion of lattice gauge theories coupled to fermions. The zero-momentum mode is remov...
