Perturbative test of exact vacuum expectation values of local fields in affine Toda theories

Abstract
Vacuum expectation values of local fields for all dual pairs of non-simply laced affine Toda field theories recently proposed are checked against perturbative analysis. The computations based on Feynman diagram expansion are performed upto two-loops. Agreement is obtained.
