Expectation values of local fields in the BulloughDodd model and integrable perturbed conformal field theories
Abstract
Exact expectation values of the fields e^{aϕ} in the BulloughDodd model are derived by adopting the "reflection relations" which involve the reflection Smatrix of the Liouville theory, as well as a special analyticity assumption. Using this result we propose explicit expressions for expectation values of all primary operators in the c < 1 minimal CFr perturbed by the operator φ_{1,2} or φ_{2,1}. Some results concerning the φ_{1,5} perturbed minimal models are also presented.
