Abstract

Exact vacuum expectation values of the third level descendent fields $< (\partial ϕ)^{3} (\partial ˉ ϕ)^{3} e^{a ϕ} >$ in the Bullough-Dodd model are proposed. By performing quantum group restrictions, we obtain $< L_{- 3} L ˉ_{- 3} Φ_{l k} >$ in perturbed minimal conformal field theories.
