摘要：

Using the exact form factors we calculate the 2 and 4-particle contributions to the current-current 2-point function in the 2-dimensional O(3) sigma-model. The results are consistent with perturbative calculations (including the use of the exact value of the mass gap) and Monte Carlo measurements.
