Title Perturbative computation of the electron g-2 using stochastic method
Abstract Numerical stochastic perturbation theory (NSPT) is a powerful numerical method to calculate perturbative series up to very high orders using lattice. We apply NSPT to the calculation of the electron g-2.This is the first example of the application of NSPT to physical observables. In our first analysis we calculate the perturbative series to the three-loop leveland show usefulness of the method. We also discuss future prospects.
