Large fluctuations in NSPT computations: a lesson from O(N) non-linear sigma models
Abstract In the last three decades, numerical stochastic perturbation theory (NSPT) has proven to be an excellent tool for calculating perturbative expansions in theories such as Lattice QCD, for which standard, diagrammatic perturbation theory is known to be cumbersome. Despite the significant succ...
