We describe a stochastic technique which allows one to compute numerically the coefficients of the weak coupling perturbative expansion of any observable in Lattice Gauge Theory. The idea is to insert the exponential representation of the link variables U µ (x) → exp{A µ (x)/ √ β} into the Langevin algorithm and the observables and to perform the expansion… CONTINUE READING
