Expectation values of descendent fields in the sine-Gordon model
We obtain exactly the vacuum expectation values $<(\partialϕ)^2 ({\bar\partial}ϕ) e^{iαϕ}>$ in the sine-Gordon model and $ $ in $Φ_{1,3}$ perturbed minimal CFT. We discuss applications of these results to short-distance expansions of two-point correlation functions.
