Instantaneous stochastic perturbation theory
arXiv:1412.5311 · doi:10.1007/JHEP04(2015)142
Abstract
A form of stochastic perturbation theory is described, where the representative stochastic fields are generated instantaneously rather than through a Markov process. The correctness of the procedure is established to all orders of the expansion and for a wide class of field theories that includes all common formulations of lattice QCD.
